Influence of soil structure interaction on the 4th story building

Design structure generally is carried out using fixed-based restraints, which assume soil is infinitely rigid. The soil has a certain rigidity and can deform a structure commonly called soil structure interaction (SSI). However, practitioners rarely consider interaction between soil and structural systems because of their high complexity and long computing time. The SSI reviews need to be carried out to obtain a more accurate analysis according to original conditions in the soil. The study aims to identify structural behavior with consideration of SSI in a case study of the 4th-story building in Pekanbaru. Structural analysis is done linearly using response spectrum analysis and nonlinear pushover analysis. Modeling was made into two types: model 1 using fixed base and model 2 using spring located on the points along the pile foundation as a representation of SSI. The analysis results show the natural period increases by 20% in the X direction and 18% in Y. The base shear decreases by 18% in the X direction and 16% in Y. The maximum displacement increases by 29% in the X direction and 24% in Y. Nonlinear pushover analysis results in an increase in the performance point value of structure with SSI modeling.

Estimating response of structures to earthquake-induced tsunami: A simple approach per unidirectional analysis

The orientation of a structure with respect to the direction of propagation of tsunami wave may often be arbitrary. As such, it may be convenient to consider the tsunami wave as a combination of two orthogonal pair. The response of structures may then be computed to the simultaneous action of two components (bidirectional) covering multiple incidence angles. However, analysis of structures in three-dimension under two orthogonal components is a daunting exercise for routine design. Against this backdrop, beginning with the validation of the simulation of tsunami against real records, a detailed scrutiny of the response of simple building frames to tsunami is made over a range of orientations per both unidirectional and bidirectional analyses. This indicates the sensitivity of response over orientations and suggests that the maximum response to a bidirectional tsunami attack can be closely estimated by unidirectional analysis at appropriate orientations. This reveals the existence of the most intense orientations in which the response to unidirectional loading may approximately represent the maximum response to bidirectional loading over all orientations. Observing statistically significant positive correlation of tsunami potential (Pd) and peak destructive potential (Id) to the response to unidirectional tsunami attacks, these pure tsunami parameters are selected as suitable intensity measures (IM). Analytical (as well as graphical through standard Mohr’s circle) expressions are then derived for the orientations in which such IM can assume the maximum. It is shown that the unidirectional analysis conducted in these orientations can closely estimate the maximum response to bidirectional attacks out of all possible orientations for single story and multistorey building frames. Hence, the straightforward unidirectional analysis in the most intense orientations may be adopted for design of coastal structures.

Passive Strategies for thermal comfort in Amazonian Cities: The Case of Tena's Waterfront"

This study explores the application of passive strategies focused on reducing urban heat islands, with special attention to improving pedestrian thermal comfort in Amazonian cities. Based on climatic data such as temperature, humidity, solar radiation, and wind speed, the impact of urban morphology on public space, particularly on the Tena River waterfront, is analyzed. Using the Grasshopper and Ladybug simulation tools, two scenarios were compared: one current, with 2-3 story buildings, and one proposed, which includes buildings up to 6 stories integrated with native vegetation. The results demonstrate that the proposed scenario not only increases shading but also significantly contributes to the reduction of temperatures, confirming the viability of these strategies to enhance sustainable urban design and improve the quality of life in Amazonian environments. The evaluation of the results highlights aspects to improve in urban development and emphasizes the importance of integrating simulation tools to design urban proposals and open spaces, guaranteeing a comfort zone for the user, encouraging pedestrian routes and therefore increasing social relations in nearby public spaces.

Optimal placement of shear wall in multistorey buildings on sloping ground

Abstract High-rise buildings most frequently use shear wall systems as one of their lateral load-resisting techniques. The great plane stiffness and strength of shear walls allow them to withstand significant horizontal loads and gravity stresses, making them particularly valuable in many structural engineering applications. The main objective of this research project is to identify the optimal position for shear walls in multistorey buildings with sloping terrain. A ten-story RCC building located in a zone IV seismically active location and slopes. An earthquake load is calculated using the comparable static technique with IS 1893 (PART–I):2016. The software utilized for these assessments was STAAD Pro V8i. An extensive investigation was carried out to examine several factors, including average displacement, period, story shear, story drift, reinforcement reduction, and G+10 story building on sloping terrain. Including shear walls has become indispensable in multistorey buildings to effectively withstand lateral forces. A comparison between the bare frame structure and the shear wall applied structure is shown.

Evaluation of household electricity consumption in multi-apartment buildings for optimization of rooftop PV systems

Empowering citizen energy communities (CECs) to produce, self-consume and share renewable energy can enhance household energy efficiency, support the adoption of renewable energy sources, reduce energy consumption and supply tariffs, and increase independence from fossil fuels. This study analyzes actual electricity consumption data from 31 dwellings in typical five-story multi-apartment buildings in Riga, Latvia, considering the potential for rooftop solar energy systems within CECs. The novelty of this study lies in the detailed analysis of household electricity consumption data and characteristics (e.g., household size, population, etc.) to predict household load which is essential for the optimal design of a multi-apartment building scale PV system. We evaluate the suitability of typical multi story buildings for rooftop photovoltaic (PV) systems, aiming to determine the potential PV performance relative to final electricity consumption. The study utilizes PolySun computer simulation software. Our findings indicate that a rooftop PV system on a typical 5 story multi-apartment building (60 apartments) can cover up to 77% of annual electricity consumption. This analysis is based on hourly real electricity consumption data. The research outcomes can inform optimization of on-site energy storage to mitigate the impact of PV systems on the grid. The proposed solution is applicable in many Eastern European countries and in some Western European countries that were influenced by the Soviet Union in the latter half of the 20th century.These regions have a similar stock of panel-constructed multi-apartment residential buildings and share comparable climatic conditions.

The Narrative Function of “Soundscape” in Eileen Chang’s Novels in the Auditory Narrative Perspective——Taking Red Rose and White Rose as an Example

Auditory narrative is the expression and writing related auditory perception in narrative works. Eileen Chang’s Novels embody rich sensory narratives and take the auditory soundscape as a typical narrative. Scholar Fu Xiuyan believes that auscultating the soundscape with auditory narrative theory can “re-listen” to the classics and achieve the purpose of admonishing the “deafness” of literary research. Based on the theory of “auditory narrative” proposed by Fu Xiuyan, this paper selects the soundscape in Eileen Chang’s typical novel Red Rose and White Rose to analyze, and further explores the relationship between Soundscape Construction and Character Creation, Soundscape Cutting and Story Building, as well as Soundscape Contrast and Aesthetic Embodiment, in order to further supplement and enrich the new issues in the new field of Eileen Chang studies.

Optimization-Based Vibration Control Analysis of Dampers in High-Rise Building

Tuned mass dampers (TMDs) are a useful control of vibrations for tall buildings and can be considered equal to burdens such as breezes and earthquakes. The better limits for TMD are to reduce the earthquake vibrations of tall buildings including soil–structure interaction (SSI) influences. This study proposes the multi-objective Black Widow Optimization (BWO) with Elman neural network (ENN) computation that is brought on to find the optimal limits of TMD. Considering that this proposed model analyzed the mass, stiffness, and damping ratio of TMD to get the maximum accelerations and displacement of 40 story building model, from the execution results, starting from this proposed BWO–Elman model to the expected methodology, the most outrageous TMD limits are better, likewise, the reduction of acceleration and displacement are 25% and 19.86% in the proposed study. This study assists the researchers with a better understanding of earthquake vibration and leads the fashioners to achieve superior TMD for tall designs. The impact of vibration control on the displacements and accelerations of both controlled and uncontrolled buildings is investigated in this work. It uses a MATLAB software technique to analyze their modal replies, moreover, this proposed optimal TMD model is compared with conventional techniques by acceleration and stiffness parameters.

Climate change impact on energy savings in mixed-mode ventilation office buildings in Brazil

With the projected increase in temperature, coupled with the rise in intensity and frequency of heatwaves caused by climate change, it has become essential to investigate the impact of climate change on building energy consumption and thermal comfort. This study focuses on office buildings with mixed-mode ventilation in Brazil as a case study. Using a typical 15-story office building archetype for various Brazilian cities, considering current and predicted scenarios (2050 and 2080), the potential for energy savings through natural ventilation was assessed. It was observed that the average increase in temperature and wind speed in the predicted climate varied in each city and showed significant variations over the years. Predicted projections under high-emission scenarios (SSP5-8.5-2080) reveal significant increases in energy consumption, highlighting the vulnerability of cities like Belo Horizonte, which could face a 77% increase in total energy consumption. Additionally, the analysis of HVAC hours of use over time indicates a progressive increase, suggesting a potential reduction in natural ventilation as a mitigation strategy. Mitigation measures, especially in the SSP1-2.6 scenario, are crucial to stabilize HVAC consumption and preserve the use of natural ventilation, emphasizing the importance of sustainable approaches to address the energy challenges arising from climate change.

Analysis of Base Shear and Story Drift in the Low-Rise RC Sructure

<p class="Abstract">Earthquakes frequently occur in Indonesia because it is an earthquake-prone area. Due to lateral load from an earthquake can cause a weakly constructed building to collapse. Designers often only consider tall buildings in designing earthquake-resistant building structures but ignore earthquake-resistant designing for low-rise buildings. This study focuses on the analysis of earthquake resistant structures with a case study of low-rise buildings in the form of a 3-story reinforced concrete (RC) building in the South Jakarta area. The objective of the study is to analyze the base shear and story drift of the structure due to lateral or earthquake loads. The structure is a reinforced concrete with the concrete compressive strength of <em> </em>= 30 MPa and longitudinal reinforcement of = 420 MPa and stirrups of = 280 MPa. This study uses equivalent static analysis manually and using ETABS 20.1.0 application. The results showed that three story buildings analyzed using equivalent static analysis method and using ETABS 20.1.0 application had almost the same results on horizontal forces with manual result of 1680.97 kN and ETABS of 1648.46 kN. The elastic story deflection and inelastic story drift in this study are still within safe limits because it is below the drift limit.</p>

Language Games- The Great Medium to Learn English Language

Abstract: The present study aims to explore the innumerable possibilities that language games create for learning a language as a supplementary material. Language games are ideal for teaching and enhancing vocabulary of ESL learners. Take something as simple as a riddle-in case the teacher asks a riddle in a second Language class, the learners are very interested in listening to it and answering it. The riddle brings enthusiasm to an otherwise silent class. In addition to it, the learners are learning the nuances of the language like figurative language unconsciously or sub –consciously. Another mind sport is quiz that can be used to teach elements of language like grammar and vocabulary and their usage. Games can also be designed to cater to the needs of the learners and enable them to enhance their language skills i.e. listening, speaking, reading and writing. A story telling activity can eventually lead to enhancement of listening skill. The chain story building technique can be used to hone the speaking skill. Similarly, cross word puzzles can also be used to remember a few facts from a lesson just read. An activity like a write up on a topic like my favourite offline/online game can enhance the writing skills of the learners. Thus, it can be concluded that language games can be used as a supportive method for teaching and learning English in ELT classroom.

Biaxial Hollow Slab Under Seismic Load

In reinforced concrete building structures, the slab is the component with the largest volume of concrete of all the superstructure components. Various innovations were carried out. Currently, the use of Hollow Core Slab (HCS) to reduce the load on building superstructures is widely used in Indonesia. Another type of slab is Biaxial Hollow Slab (BHS) as an alternative to reduce slab concrete volume. BHS is considered capable of reducing concrete consumption by up to 30% -50% of conventional concrete without reducing the performance of the slab itself. It could be reducing the load on the working superstructure can reduce the influence of seismic loads on the foundation. Indonesia is a country with an earthquake zone, so the use of BHS must be considered with seismic design categories that are appropriate to the earthquake zones in Indonesia. This research is focused on giving information about the numerical study of application BHS in 10th story building with design seismic category D. The thickness used in this study is equivalent thickness of BHS to solid slab. The absence of beams in weak axis and the present of perimeter beam by utilization BHS, gives the result BHS has sufficient capacity to carry the workload.

Reliability-based optimization of supported pendulum TMDs’ nonlinear track shape using Padé approximants

Supported Pendulum Tuned Mass Dampers (PTMDs) are vibration absorbers whose mass is constrained to oscillate along a curved path, enabling to use gravity as a restoring force. Through a proper track shape selection, they can adapt to the so-called Nonlinear Energy Sinks (NES) concept, consolidated for spring–mass–damper TMDs. Accordingly, NESs are recognized for their ability to resonate in a wide range of frequencies due to their nonlinear nature, becoming more effective when variations on the host structure’s natural frequencies occur. However, regardless of the recent advances in the last few years, gaps remain to be explored in the track shape optimization of supported PTMDs. For instance, a comprehensive literature review shows that Reliability-Based Design Optimization (RBDO) studies to determine the track shape of supported PTMDs cannot be found to the best of the author’s knowledge. Within this context, this paper proposes an original RBDO approach to define the track shape of supported PTMDs in buildings subjected to seismic excitation. For this purpose, a generic rational function with an arbitrary curvature, determined from the Padé approximation of the circle equation, is constructed to allow the PTMD’s path shape search. This procedure allows optimizing fewer parameters than required in Taylor series expansions while providing a wider range of alternatives for numerical optimization. Finally, an active-learning Kriging-based Efficient Global Optimization (EGO) procedure is employed to find the optimum solutions with few objective function evaluations. The application case consists of a typical soft story building subjected to seismic loadings. The optimal track differs from the circle equation, with a higher slope for moderate displacements.

SEISMIC ANALYSIS OF MULTISTORIED OPEN GROUND STORY BUILDING WITH DIAGONAL STRUT AND SHEAR WALLS

The Open Ground Story (OGS) building is a functional need of all urban areas so cannot be eliminated. According to studies from previous earthquakes, when there is severe earthquake shaking, Reinforced Concrete (RC) frame buildings with open ground levels function badly. In this work, four models of G+14 RC frame buildings with and without a shear wall, coupled sheal wall, and diagonal strut were modeled and analyzed using ETABS-2018 software's static and dynamic response spectrum method. Model 1 open ground story RC building without strut and the shear wall was compared to the other three models that included a shear wall, coupled shear wall, and diagonal strut. As a result of the findings, it has been determined that shear wall, coupled shear wall, and diagonal strut not only increased the stiffness but also reduced displacement. A model with a combination of shear wall and coupled shear wall showed a minimum base shear and overturning moment than all other models.
