Endoscopic anatomy of the ventricles

The cerebral ventricles are structures known since antiquity. At the beginning of its description there was a belief that human thoughts and intellect were generated inside the ventricular cavity, and this idea persisted even after the Renaissance. In this period after the Dark Ages, the anatomical description of the ventricles evolved a lot, but it took a long time to conclude the true liquid nature of the ventricular content. The ventricles are divided into lateral, third and fourth ventricles, and each of these regions presents communications between themselves and very precise limits. For endoscopic procedures, a thorough knowledge of the anatomy of the lateral and third ventricles is extremely important. The cerebrospinal fluid circulates inside the ventricles according to a complex mechanism, and there are still controversies nowadays, especially regarding its resorption. Each lateral ventricle is a “C”-shaped cavity that surrounds the thalamus and is deeply located in the brain, following the contour of the choroid fissure. These structures represent, from an embryological point of view, the light of the telencephalic vesicles. Each lateral ventricle has five parts: frontal horn, body, atrium, occipital horn, and temporal horn. The frontal horn is the part of the lateral ventricle located anteriorly to the foramen of Monro. The lateral ventricle body extends from the posterior margin of the foramen of Monro to the point where the fornix and the corpus callosum converge, thus disappearing the septum pellucidum. The atrium of the lateral ventricle and its occipital extension form a triangle with an anterior base in the pulvinar and a posterior apex in the occipital lobe. The occipital horn is triangular, with a posterior vertex and a base in the atrium. The temporal horn is the inferior extension of the ventricle, being the continuation of the atrium, directing itself anteriorly and laterally. Each of these divisions has a medial, lateral, ceiling, and floor wall. In addition, the frontal, temporal, and atrial horns have anterior walls. These walls are formed by the thalamus, septum pellucidum, white matter, corpus callosum, caudate nucleus, and fornix. The third ventricle is a funnel-shaped, unilocular, narrow midline cavity. It communicates at the anterosuperior margin with each lateral ventricle through the foramen of Monro and, subsequently, with the fourth ventricle through the cerebral aqueduct. In adult individuals, the lateral distance of the third ventricle is 5.5 mm on average. In a study using MRI images, the hydrocephalic configuration of the third ventricle disappeared after the endoscopic third ventriculostomy (ETV), with a decrease in diameter, elevation, and horizontal direction of the floor and reduction of the infundibular angle . The floor of the third ventricle extends from the optic chiasm anteriorly to the opening of the cerebral aqueduct posteriorly. It descends ventral and is formed by at least 12 cellular clusters or nuclei within the hypothalamic region. Anatomically, three portions can be described on the floor of the third ventricle: (1) premammillary portion, which extends from the infundibulum to the premammillary sulcus, constituting a very thin layer of gray substance of the hypothalamus; (2) interpeduncular portion, which extends from the postmammillary recess to the posterior margin of the interpeduncular space, being formed of gray substance and firmer than the first; and (3) peduncular portion, which corresponds to the portion of the cerebral peduncles, being the most solid portion, being formed by the medial aspect of the peduncles covered by the peduncular ependyma. The knowledge of the endoscopic anatomy of the ventricles is of the key importance for endoscopic neuroendoscopy

BILATERAL DECOMPRESSIVE CRANIECTOMY IN A PATIENT WITH HEAD INJURIES DUE TO GUN PROJECTILE: A CASE REPORT

A 38-year-old male patient with multiple skull injuries caused by a small-caliber firearm projectile whose entry hole was the right eye after being attacked when leaving his home. Consequently, he presented head trauma with multifragmented fracture of the cranial vault causing exposure of the brain mass in the bilateral frontoparietal region and complete injury to the right eyeball with fracture of the orbit in its posterior, lateral, medial, roof and floor walls. He was transferred to the General Hospital of Axapusco, where the patient was received with 8 points on the Glasgow scale and a simple tomography of the skull was performed, observing injury to both hemispheres, bilateral subarachnoid hemorrhage, parasagittal hemorrhagic contusions and cerebral edema, predominantly affecting to the corpus callosum and cingulum. Therefore, hinge-type decompressive craniectomy and debridement in the first 12 hours of trauma were determined as surgical treatment. It should be noted that a favorable recovery was obtained without associated complications. It is concluded that the surgical treatment of choice is early decompressive craniectomy when the patient presents less than 9 points on the Glasgow Coma Scale at admission, the injury along the path of the wound is bihemispheric and posterior fossa, the time that elapses from the injury to the performance of the surgery is within the first 12 hours, there is pupillary reactivity and the age of the patient is greater than 35 years.

既存壁式鉄筋コンクリート造建築物において下階壁面内に施工される接着系あと施工アンカーの引張特性に関する実験的研究

For the renovation of the reinforced concrete boxed-wall building, a new opening would be constructed on multi-story wall frame, and local retrofit with post-installed adhesive anchors would be applied. In this study, evaluation method of tensile strength for a post-installed adhesive anchor embedded in wall plane was proposed. The non-fixed bond-tensile test of anchor specimens embedded in wall-slab specimen was conducted. The parameter of specimens are embedment length of anchors, wall thickness, and wall shapes. Tensile strength of the anchors could be evaluated due to previous formula with the assumption of the effect of local retrofit on bottom floor wall and floor slab.

Septic shock induced by latent odontogenic orbital infection: a case report

A 65-year-old patient was admitted to the hospital due to proptosis of the left eye accompanied with ophthalmodynia and toothache for two months. Ophthalmic examination revealed a palpable mass around the lateral orbit and temporal fossa, and maxillofacial CT suggested a malignant tumor invading the left orbital floor wall. One week later, the patient was diagnosed with left orbital cellulitis and septic shock due to peri-orbit redness, eyelid edema, chest tightness, nausea, vomiting, hypotension, and a marked increase in peripheral blood neutrophil count. The infection was well controlled after remission of shock, anti-infective therapy and surgical drainage. At 2 months after surgery, the surgical incision of the upper eyelid skin recovered well and the best corrected visual acuity of the left eye was 1.0.

The role of triangular space of ear canal-parotid-mastoid in the surgery for first branchial cleft anomalies

Objective:To explore the role of triangular space of ear canal-parotid-mastoid in the operation of the first branchial cleft deformity. Methods:The clinical features and intraoperative characteristics of 25 cases with first branchial cleft anomalies who underwent surgery from September 2011 to September 2019 were analyzed, and the role of the triangular space of ear canal-parotid-mastoid in the surgery was explored. Results:Following dissecting and lesions removel of the triangular space of ear canal-parotid-mastoid, all the lesions were resected completely. Eighteen cases had fistula in the floor wall of ear canal, seven cases had duplicated of external auditory canal in the inferior of the floor wall. The recurrent cases were all attributable to the residual lesions in the triangular space. There was no recurrence, salivary leakage or stenosis of external canal. One case suffered from HB2 level facial paralysis. Conclusion:Surgery is the optimal treatment for first branchial cleft anomalies. Following the active dissection of the ear canal-parotid gland-mastoid space and depending on the microscopic operation, the deep lesions would be exposed clearly and the facial nerve could be marked and protected. Cleaning this triangle space can lead to completely lesion removal, avoid facial paralysis, salivation and recurrence.

Analisis Kualitas Fisik dan Risiko Kontaminasi Terhadap Kandungan Bakteriologis Pada Sumur Gali di Wilayah Kerja Dinas Kesehatan OKU 2021

The decline in the quality of clean water used by the community due to contamination of dug well water which allows the development of various types of bacteria. One of them is coliform bacteria. The formulation of the problem in this study is whether the physical factors and the risk of contamination can be known to be related to the bacteriological content of dug wells. This study aims to analyze the physical factors and risk of contamination of the bacteriological content of dug wells. The research design used was cross sectional. This research was conducted in the work area of the OKU District Health Office in 2021. The population in this study was dug wells that had been carried out by an Environmental Health Inspection (IKL) and a sample of 57 dug wells. The study was conducted from June 2021 to July 2021. The analysis was carried out using the chi square test with a significance level of p value 0.05. The results showed that there was no relationship between cloudiness (p value = 0.308), odor (p value = 0.308), taste (p value = 1,000), and color (p value = 0.568) on the bacteriological content of dug wells, and there was a relationship between risk of contamination (p value=0.048) on the bacteriological content of dug wells. The results of multivariate analysis showed that there was no dominant variable with bacteriological content in dug wells. The conclusion in this study was that there was no relationship between turbidity, odor, taste, and color variables with bacteriological content of dug wells. There is a relationship between the contamination risk variables and the bacteriological content of the dug wells. And there is no dominant variable affecting the bacteriological content of dug wells. This study suggests that the OKU district health office can improve public knowledge by way of health education and seminars, especially about the quality of dug wells and to the community in order to improve the physical condition of dug wells such as lips, floor walls, and sewerage for the high category while for the low category must be checked.

Role Of Cbct In The Treatment Of Orbital Floor Blow Out Fractures In Children

Background, Aim, and Objectives: Orbital floor blow out fractures are uncommon in children but can present with a dilemma in the Emergency department upon presentation. We collected case reports of 17 cases over a three-year period. The patients were selected from the age group six to 13 years of age with history of trivial blunt orbital trauma. The main complaint was mild pain in the eye upon presentation. Five patients were having clinical presentation of oculo-cardiac reflex. The suspected patients underwent Cone Beam CT of the midface with multiplanar cone beam reconstruction which confirmed the diagnosis of orbital floor fractures with trap door defect or minimal displacement and in a few cases inferior rectus entrapment. Orbital floor trapdoor fractures have oblivious features upon presentation and can easily be overlooked if not evaluated managed by expert healthcare providers which can lead to significant morbidity and even mortality in patients with oculocardiac reflex. Cone Beam CT of mid face with multiplanar reconstruction is the standard of care in the diagnosis and management of white eyed blow out orbital floor fractures in the provision of evidenced based healthcare practice. Methodology: This is a retrospective cohort study to evaluate the results of pediatric age group with trapdoor and blow out orbital floor fractures who underwent CBCT for the diagnosis and further management. Seventeen cases were selected who were in the age group between 6 to 13 years.12 cases underwent surgery for orbital floor exploration and nine were having inferior rectus muscle entrapment which was released. Five patients were managed non surgically. Result: One patient disappeared in this group during one-year post-operative follow up. No residual defect was found in the remaining sixteen patients. Cone beam Computer tomography with multiplanar reconstruction should be the standard of care for the diagnosis and treatment of blow out and trapdoor orbital fractures. Strength and limitations: Although this study is of a limited number of pediatric patients, but it highlights the significance of CBCT in the management of trapdoor and blow out orbital floor fractures in children. Further studies are needed to elaborate the utilization of CBCT in the treatment of orbital floor and medial orbital wall fractures. Conclusion: Our study suggests that CBCT has a higher value of specificity and less radiation exposure in the diagnosis of orbital fractures in pediatric age group when there is isolated orbital or mid face trauma, and CT brain is not recommended. Cone Beam CT with multiplanar reconstruction is considered the standard of care in the diagnosis of white eyed blow out orbital floor fractures in the provision of evidenced based healthcare practice. Perioperative CBCT and navigation should be universalized to achieve the best outcome.

EFFECTS OF A PILLARLESS, CENTER-OUT STOPING PATTERN ON HAULAGE DRIFT PERFORMANCE AND ORE TONNAGE AT RISK

With respect to mining sequence, this article intends to investigate the impact of pillarless centre-out stoping patterns (e.g. pyramidal sequences) on the performance of mine haulage drifts (e.g. ore access units), the tonnage of unmined ore at risk, and the required quantity of fill material. Using RS2D software, a two-dimensional, elasto-plastic finite-element model for a haulage drift located at 1200m below the surface in the orebody’s footwall has been built. The spread of yielding zones into the rock mass around an access drift and unmined stopes is used to assess mine haulage drift stability and estimate the amount of unmined ore at risk owing to local mining activity. The findings are presented and discussed in terms of the size of failure zones, the number of tonnes of unmined blocks at risk, and the amount of backfill materials required, all in relation to the mining stage. The findings show that haulage drift stability is rapidly diminishing. The drift roof begins to deteriorate at an early stage (after mining step 3). In the drift roof, left wall, floor, and right wall, failure zones measured 1.55m (step 3), 2.28m (step 4), 2.57m (step 5) and 1.88m (step 5) accordingly. After mining step 4, there was a total of 905 m3 of unmined ore at risk (4100 tons), and after mining step 5, a total of 1500 m3 (30 tons) of back fill material was required to strengthen stopes.

RISK ASSESSMENT IN 13-STORY BUILDING PROJECTS WITH THE FAILURE MODE AND EFFECT ANALYSIS (FMEA) METHOD AND THE DOMINO EFFECT

The building construction project is one of the activities that can pose a safety risk. Work safety risk assessment can be done using the Failure Mode and Effect Analysis (FMEA) method and looking at the Risk Priority Number (RPN) value. The purpose of this research is to take a case study of the building Office in determining the highest RPN and provide recommendations on its management. This project consists of 13 earthworks, passenger hoist, tower crane, scaffolding jobs, ironworks, formwork work, foundry work, mechanical, electrical plumbing (MEP) work, welding work, and floor wall doing works, and ceramic installation work. The highest RPN from the observations occurred in Iron Fabrication which can cause fingers hit by a bar cutter and bender. In this case, personal protective equipment (PPE) is significant in preventing these impacts from occurring in the project work area.

Numerical Analysis of the Structural Resistance and Stability of Masonry Walls with an AAC Thermal Break Layer

Since energy efficiency has become the main priority in the design of buildings, load-bearing walls in modern masonry constructions nowadays include thermal break elements at the floor–wall junction to mitigate thermal bridges. The structural stability of these bearing walls is consequently affected. In the present paper, a numerical study of the resistance and stability of such composite masonry walls, including AAC thermal break layers, is presented. A finite element mesoscopic model is successfully calibrated with respect to recent experimental results at small and medium scale, in terms of resistance and stiffness under vertical load with or without eccentricity. The model is then used to extend the numerical models to larger-scale masonry walls made of composite masonry, with the aim of investigating the consequences of thermal elements on global resistance and stability. The results confirm that the resistance of composite walls is governed by the masonry layer with the lowest resistance value, except for walls with very large slenderness and loaded eccentrically: composite walls with low slenderness or loaded by a vertical load with limited eccentricities are failing due to the crushing of the AAC layer, while the walls characterized by large slenderness ratios and loaded eccentrically tend to experience buckling failure in the main clay masonry layer.

Blowout Fracture Assessment Based on Computed Tomography and Endoscopy: The Effectiveness of Endoscopy for Fracture Repair.

The purpose of this study was to compare the configuration of blowout fracture observed through orbital computed tomography (CT) and endoscopy, then present the effectiveness of using an endoscope in reconstruction surgery of blowout fracture. We retrospectively reviewed the clinical records of 337 patients who underwent reconstruction surgery of blowout fracture between January 2017 and December 2020 in the Department of Ophthalmology at Korea University Guro Hospital. The patients were categorized into 3 groups based on preoperative CT findings as follows: combined orbital medial and floor wall fractures, trapdoor fractures, and large blowout fractures. The images obtained through CT and endoscopy were compared among the 3 groups. Endoscopy helped identify herniated soft tissue and posterior fracture margins, and it also provides better magnification and a brighter view of the posterior aspects of the fracture site. Furthermore, endoscopy can also provide educational opportunities to visualize the fracture site and help trainees understand the surgical procedure approach or orbital anatomy. Based on our results, we suggest using an endoscope during blowout fracture surgery as an effective approach to reduce postoperative complications due to endoscopy's advantages in clear visualization of the fracture site during operation.

On the mechanical performance of honeycomb-core sandwich L-joint under bending load: an experimental-numerical study

The mechanical properties of sandwich structures have drawn much attention from research and industrial application, while sandwich structures in the form of L-joint have been rarely addressed. In this paper, L-joint sandwich structures were experimentally tested under bending load to investigate the mechanical performance during structural deformation and damage evolution. The corresponding testing process was numerically simulated using finite element (FE) modeling. Nomex® honeycomb was selected as the core material of the sandwich structure, with the outer facesheets made of thermosetting Carbon Fiber Reinforced Polymer (CFRP) prepreg. Sandwich structures in the form of thin-walled beams and L-joint were then manufactured with specially-designed molds. Quasi-static three-point bending tests up to failure were conducted on the sandwich panels. Experimental results revealed that the main failure mode of the sandwich panel was the fracture in the honeycomb wall. The stiffness and strength properties of the sandwich structure were analyzed with FE modelling results, which showed good agreement with the experimental data. The adhesively bonded and hybrid rivet-bonded sandwich L-joints were investigated under vertical crushing load, showing the main failure region located in the corner area of the L-joint. The proposed experimental-numerical method on the mechanical performance of sandwich structures can provide reliable guidance on the connection of the caravan floor and side walls in automotive industries.

ЧИСЛЕННОЕ МОДЕЛИРОВАНИЕ ПЫЛЕВОЗДУШНЫХ ТЕЧЕНИЙ ВБЛИЗИ МЕСТНОГО ВЕНТИЛЯЦИОННОГО ОТСОСА ОТ СВЕРЛИЛЬНОГО ОБОРУДОВАНИЯ

A significant amount of dust is released during the drilling process. It negatively affects the cleanliness and ecology of the surrounding space, as well as human health. The design of a local extraction nozzle is proposed for dedusting the process of drilling concrete with standard drills. A computer model of the dust-air flow in the developed nozzle is created in the software package SolidWorks Flow Simulation. The dynamics of dust particles formed during drilling is numerically studied. The behavior of dust particles of different sizes is considered. It is proposed to use the value of the maximum diameter of dust particles completely captured by the suction channel as a criterion for the efficiency of dust particle capture. Three variants of the drilling plane arrangement are considered: floor, ceiling and vertical wall. The dependences of the maximum diameter of dust particles on the intake air flow rate, the distance of the extraction channel on the side surface of the nozzle to the place of its abutment to the drilling plane, and the radius of the suction channel are determined. The results obtained can be used to design and improve systems for capturing dust pollution generated during drilling. The formulated further directions of research are useful for researchers engaged in identifying the processes of capturing dust particles from mobile technological equipment.

Evaluation of Sexual Dimorphism in Schneider Membrane Thickness Using Cone-Beam Computed Tomography (CBCT) for its Clinical and Forensic Implications

Sinus augmentation requires careful manipulation of the Schneider membrane. Perforation of the membrane can be a challenging complication. The objective of this study is to evaluate the sexual dimorphism of Schneider membrane (sinus membrane) using cone-beam computed tomography (CBCT) imaging modality and discuss its clinical applications vis-a-vis the sinus lift procedure for dental implants and also its forensic implications. One hundred CBCT scans in the maxillary first molar region of fifty men and fifty women in the age group of 25–50 years were examined at two standardized points on the floor and lateral wall of maxillary sinus, and its mean was obtained. Measurements were taken for thickness of sinus membrane at most prominent antero-posterior and mesio-distal dimensions. The mean sinus membrane thickness and correlation in age groups (25–35 and 36–50 years) of both the genders were evaluated statistically. The results showed a thicker sinus membrane in women, especially in 36–50 age group than that of men. This study correlates the thickness of the sinus membrane with gender dimorphism and delves on its association with the risk of perforation during sinus lift procedures and also its forensic implications.

On the guiding principles in the choice of methods for restoring the broken integrity of the pelvic floor and abdominal wall

Mm. Yy! In embarking on the flattering and at the same time responsible duty of delivering a speech at the annual meeting, which is imputed by society to its elected representatives, I believe that the most appropriate topic for such speeches should be considered questions of principle, widely affecting one or another department of our specialty. Having outlined it comprehensively, the speaker's task is mainly reduced to comparing what is already firmly in the sense of scientific and practical with the side of the matter that, while still being controversial and open, awaits resolution and needs development or reform. Naturally, the broader the theme is, the more difficult it is to give it perfect lighting. Being fully aware of this position, I nevertheless outlined in my today's speech the question of "the guiding principles in the choice of methods for restoring the broken integrity of the pelvic floor and abdominal wall." Choosing such a question as a topic for my speech, I was guided by the following considerations: firstly, in essence, being, so to speak, general, it should be of interest to all those taking part in the meeting, especially since this issue is important not only for its purely scientific interest , but it also affects the practical aspects of life, with which the gynecologist has to meet at every step; in 2, those purely scientific foundations, not only clinical, but anatomical and physiological, which must inevitably be taken as the basis of practical conclusions and conclusions, are too ignored and the whole issue from the principled side is not covered to the extent that it is absolutely necessary for the success of practical conclusions: positions and conclusions based on hasty empirical conclusions are accepted too easily and are not sufficiently supported not only by scientific data, but represent large gaps in the sense of further clinical observations. In 3, I was guided by the desire to present in the system the rich material that is at my disposal in the Imperial Clinical Institutes, Midwife and V. Kn. Elena Pavlovna, mainly in the sense of the results achieved, especially since at different times I myself, as well as my assistants in clinical activities, have had occasion in recent years to speak to you with reports on individual particulars of the issue I have raised today.

Time-dependent deformation and fracture evolution around underground excavations

A numerical time-dependent deformation model of rock by incorporating the stress corrosion model into a three-dimensional discrete element code was established to investigate time-dependent deformation and fracture evolution of surrounding rock around underground excavations with circular, inverted U-shaped and rectangular cross-sections. The mesoscale model input parameters were calibrated to replicate the mechanical behavior and failure patterns of the rock observed in laboratory. Numerical simulations on the time-independent and -dependent deformation and fracturing evolution of the rock around underground excavations with different shapes under hydrostatic stress were studied. The results show that the maximum time-independent displacements of circular, inverted U-shaped and rectangular openings are 11, 15, and 34 mm at left roof, right floor and left side, respectively. It shows that the surrounding rocks around the circular, inverted U-shaped openings are much more stable than that around the rectangular opening. The cracks within the surrounding rock around different shaped openings gradually increases as time goes by, and the tensile cracks are dominant. The progressive failure process of the circular openings under varying lateral pressures was further modeled. The results show the failure zone at the roof wall and floor wall becomes more evident with an increase in the lateral pressure coefficient.

Influence of air shock wane on buildings and structures

The destruction of buildings and structures occurs as a result of natural disasters, accidents, or terorist attactacts which in many cases are accompanied by explosions.
 The action of an air shock wave on a building is characterized by a complex set of loads: excess pressure, reflection pressure, velocity pressure, leakage pressure, load from seismic waves.
 Ensuring the preservation and restoration of buildings and structures includes measures to assess the possible degree of destruction of buildings and structures. Therefore, in modern conditions, the design of buildings, structures and their elements is not possible without taking into account the dynamic effects. When designing and constructing buildings and structures, it is always necessary to take into account the resistance of structural elements to the action of damaging factors, both the explosion in general and the shock wave of the explosion in particular, which will help avoid future possible human losses.
 Therefore, the article considers the general characteristics of the processes of interaction of the air shock wave with the building, the method of calculating the time of destruction of prefabricated buildings and the main parameters of the air shock wave which flows as a result of an explosion in a building, structure with windows, doorways and openings, which arose as a result of the destruction of floor structures or walls.
 Studies have shown that the load on the structure depends on the parameters of the wave that flows through the holes in the buildings and through the holes formed by the destruction of the walls of the building, the comparison of calculated and experimental data indicates their sufficient convergence.

Reconstruction of the Orbit

Orbital defects require careful consideration due to the need to protect globe position and visual function. The orbit’s unique geometry requires working within a confined space. When indicated, orbital rim fractures or segmental defects can be reconstructed using low-profile, titanium mini-plates. Multiple implant options are available to support the globe when defects involve the orbital floor or medial wall. These materials should be able to contour to match the concavity of the orbit, thereby avoiding changes in orbital volume. For complex defects, virtual surgical planning strategies, including intra-operative navigation or the use of anatomic models for pre-operative plate bending or cutting guides for secondary osteotomies, can improve precision and reduce operative time. This chapter will describe operative indications and practical management options for orbital defects. This review contains 7 figures, 1 video, 2 tables, and 38 references. Keywords: orbit anatomy, periorbital trauma, orbital reconstruction, craniofacial imaging, alloplastic implant, mini plate, surgical approach, virtual surgical planning

Seismic Behavior Research and Strengthening Measures of Bottom Frame--anti-seismic Wall Masonry Structure

In this paper, the mechanical characteristics and seismic performance of the bottom frame anti-seismic wall structure are analyzed. According to the calculation formula given in the code, the calculation and analysis of the four story store house with the bottom one story frame are carried out. Under the minimum material strength specified in the code, the floor stiffness ratio, equivalent stiffness, wall and frame seismic action of the bottom story are calculated. At the same time, the type, the material strength and the restrained anti-seismic wall are calculated. The results show that the number of the seismic walls has a great influence on the effective stiffness of the bottom floor, the stiffness ratio between floors, the seismic action of the wall and the seismic action of the frame column, and the key influencing factors are determined. The conclusions are as follows: by increasing the concrete strength of the seismic wall at the bottom, the stiffness of the bottom floor is increased; the strength of the block is increased, and the seismic shear allocated to the column is reduced; the number of the seismic wall has a great influence on the seismic action of the frame column at the bottom. The influence of the stiffness ratio between layers is small; the use of reinforced concrete seismic wall can optimize the stiffness ratio between layers, reduce the number of the wall, and provide a reference for the selection of engineering reinforcement scheme.
