Research on Design and Analysis of Multi-Story Building by using AutoCAD and STAAD-Pro

“The population of India is the second highest in the world as per the 2022 report” [1]. In order to live well, there is an increasing demand for adequate infrastructure. People are migrating from rural to urban regions. Problems will rise due to the high population in urban areas. Due to a lack of available land for construction in metropolitan areas, high-rise building structures are becoming more necessary to address the population density issue. High-rise structures are in high demand, and their construction must be completed without compromising any of the three criteria of cost, timeliness, and safety. AutoCAD design software enables the production of both 2D and 3D drawings for use in constructing multi-story buildings. This study aims to utilize the software package STAAD-Pro to analyze and design a multi-story building, following the production of 2D and 3D drawings using AutoCAD. STAAD-Pro offers a far quicker method of structural analysis and planning for the likelihood of the fewest faults. The design involves load calculations and analyzing the whole structure by STAAD Pro. “The method used in STAAD Pro analysis is Limit State Design followed by Indian Standard Codes. The loads considered for designing the building are dead loads, live loads, and Wind loads. For analyzing a multi-storied building, one has to consider all the possible loadings and see that the structure is safe against all possible loading conditions” [2]. The aim of this study is to analyze the structural behavior of the building and ensure that it meets the necessary design standards and codes. To remain competitive in the constantly expanding market, it is crucial for structural engineers to optimize their time management. This study highlights the importance of using advanced software tools in the design and analysis of complex structures to ensure their safety and stability.

Analysis of Multi-Storey Buildings and Occupational Safety in an Environmental Law Perspective

The rapid development of the construction industry in addition to providing benefits also poses considerable risks, where this industry can be said to be vulnerable to work accidents (Ervianto, 2005). Occupational accidents in construction projects will be detrimental to the workforce, an unsafe and unhealthy work environment will also impact on the disruption of the workforce's performance. Based on the results and discussion of the researcher, namely the analysis of multi-storey buildings and work safety in the perspective of environmental law in the Kotamobagu City Library Building, the researcher sees in general that the construction of the Kotamobagu Library multi-storey building, both theoretically and the construction of the building has complied with the rules in the laws and regulations invitation contained in Law Number 28 of 2002 concerning Buildings. The Kotamobagu City Library Building also in its work has implemented the Occupational Safety and Health Management System in the Kotamobagu City Library Building Project very well. This can be seen by the K3 management procedures and K3 laws and regulations issued by the government and also by companies. The application of legal aspects to Occupational Safety and Health affects both the company and the workforce because if the company or workforce ignores OSH in carrying out their work they will be given legal sanctions because both the company and the workforce are legally bound. For example, if workers are working at heights and do not use seat belts, the safety officer can give sanctions to these workers according to the rules made by the company. Implementing K3 in accordance with statutory regulations can indirectly prevent the company from occurring accidents and occupational diseases as well as work violations. And also work can be carried out safely and efficiently. The researcher also draws the conclusion that the construction of a multi-storey building, Kotamobagu City Library Office built by the Kotamobagu Regional Government is in accordance with laws and regulations regarding environmental aspects. PP No. 27 of 1999 concerning Amdal. Law No. 22 of 2021 concerning Implementation of Environmental Protection and Management. PP No. 27 of 2012 concerning Environmental Permits and several other regulations which are not mentioned in the results of this study but are a source of reading for researchers. Apart from that, the Kotamobagu City Library Office Multi-storey Building has also met the green spatial requirements in urban areas.

Seismic analysis of Multi storey Building on Sloping Ground and Flat Ground by using ETABS

Due to urbanization and industrialization, which paved the door for the development of tall, multi-story structures on mountainous terrain, land is scarce in emerging nations like India. Buildings built on hilly terrain differ from those built on flat terrain due of their uneven and asymmetrical vertical and horizontal structures. These buildings are also significantly more vulnerable to earthquake pressures when located in mountainous terrain. The primary goal of the current endeavor is to investigate how structures behave on level and sloping terrain. Hilly places require different construction configurations than level areas. Hill structures vary from those on lowlands in that they are torsionally linked, highly irregular, and asymmetrical in both the horizontal and vertical planes. As a result, they are vulnerable to severe damage when an earthquake strikes. The behavior of a multi-story structure with two distinct slope angles was attempted to be studied in this paper, and a comparison with flat ground was made. by taking Earthquake Zone II into account. Buildings on level ground and buildings on slanted ground are compared. The models are created with the aid of the structural analysis program ETABS. Response spectrum analysis is used for analysis. The analysis’s findings, including storey shear, storey drifts, moments, and displacement, are tabulated and examined.

Comparison of Seismic Analysis of Multi storey Buildings with RCC columns and CFST columns by Varying Heights

As there is an increase in population day by day, there is more requirement for land. But the availability of land on Earth’s surface is 29 % which should be used for various purposes and hence, there would be difficulty in providing accommodation to all the citizens. There comes the idea of vertical development of the structures i.e., multi-story structures. Usage of Reinforced Cement Concrete (RCC) for high rise structures with large spans would be very complex as it requires high grade concrete and steel and hence becomes risky. In that case, the composite structures give effective results due to the co-action of materials. Providing Concrete Filled Steel Tube (CFST) columns will reduce the requirement of formwork and will increase the functional area as the steel tube acts both as longitudinal as well as transverse reinforcement which gives mere resistance to tensile stresses. In this thesis, Multi Storied Structures of G+10, G + 20 and G + 30 were taken and variation was considered in the columns, the rest of the structural elements have been taken of RCC only. The seismic analysis of the structures has been carried out for both the type of structures for each height by using Response Spectrum analysis in Zone II following the guidelines of IS 1893:2016 code using ETABS software. The comparison of the structures has been shown in terms of earthquake response parameters such as story drift, story displacement, story shear etc. It has been concluded that structures with CFST columns have shown better seismic performance with increasing height compared to RCC structures.

Analysis of Multistory Buildings With Stub Column In Different Seismic Zones In India – A Review

Construction of building requires proper planning and management. Buildings are subjected to various loads such as dead load, live load, wind load and seismic load. Seismic load has extreme adverse effect on building so it is necessary to perform seismic analysis. This paper explains about the response of building when it is subjected to seismic load, this response can be shown by story drift and base shear. Behavior of buildings with stub columns is analyzed and the results are compared with buildings without stub columns. Seismic analysis has been performed on (G+7) buildings located in seismic zones 2,3,4&5 using ETABS software. Analysis has been performed according to IS 1893:PartI (2002).The storey drift and design base shear are evaluated and compared. Pushover analysis was performed and the results were compared.

Seismic Analysis of Multi Storey Buildings With and Without Shear-Walls

A structure in its design life period is subjected to a number of earthquakes of various intensities from small to medium and large. The work of a structural engineer is to come up with a design that will be able to resist the impact of earthquake without collapse. Earthquake resisting members like shear-walls are ductile in nature and they exhibit enough resistance to face the seismic forces and reduce the amount of drifts and displacements. In this study, an under 50m category building (twelve storey, G+11, total height 36m) and a 50-100 m category building (twenty-eight storey, G+27, total height 84m) are considered with and without shear-wall configuration for seismic analysis. Both static and dynamic analysis are applied to the structures using ETABs software. Difference in results for drifts and displacements are studied in this investigation.

Application of 3D Laser Scanning for Digitization, Design and Analysis of Multistoried Building

Laser scanning is a fast-developing technology, which collects millions of points and creates a framework within a few minutes, generating a 'point cloud' of the structure. Laser scanning is a quite new but rapidly evolving technology that has been reviewed. this research study has used most modern models of laser scanners and their accompanying software that are capable of accurate capture and alignment of point clouds. Consequently, the laser scans have precisely captured the current geometry of each structure, which is irregular in many cases due to inherently complex geometry, anomalies during the original construction, aging, deterioration, and structural damage. As both the exterior and interior of the structure have been scanned, the point cloud became a digital 3D image of the historical building, which can be virtually toured from inside and outside. A 4-story public building was scanned using a 3D laser scanner to determine the architectural and structural drawings of the response to an earthquake. The application of passive control using a damper with the laser scanner has been modelled in this study. The results corroborate that this technique provides the best outcomes for reducing seismic damage collapses.

Seismic Analysis of Multi Storey Building Using Strong Column Weak Beam Ratio (SCWB) in Different Zones of India

An earthquake structures are mandatory to avoid significant damages (i.e., collapse) and aims that structure withstand a major earthquake without collapse. The design approach adopted is to ensure that the columns of the structure more capable to resist moments than beam; to avoid progressive collapse of structure due to failure of columns in lower level; it is necessary the columns have stronger than beams (strong column weak beam). The concept of SCWB is to ensure that plastic hinge formed in the beam not in the column; this help in dissipating the more energy along with providing ductility to the structure. If the plastic hinge is formed on the both ends of column then, the column is not able to spread the plasticity and collapse which are leads to global failure. The failure modes in all past earthquake is exactly opposite i.e, strong beam weak column; and comes to sway mechanism and fails to collapse. For this it is foreseen that the values of ratio of Mc/Mb (ratio of sum of ultimate moment of resistance of columns to sum of ultimate moment of resistance of beam) in the beam-column joint are stated by many design codes and the values are different ranging from 1.2,1.3,1.4,1.5 to 2, etc. Another effect of ratio Ic/Ib (ratio of moment of inertia of column to moment of inertia of beam) have been studied but the exact meeting of SCWB behaviour in the structures at the time of collapse not stated clearly. The Mc/Mb and Ic/Ib ratio are very important to prevent damage in the structure under seismic action. In the present work, attempts are made to achieve exact ratio of exact strong column weak beam. In this study, the combined effect of two ratio (Mc/Mb, Ic/Ib) simultaneously investigated in different zones of India to find out exact SCWB ratio’s value for to meet the SCWB behaviour. Different numerical examples are presented of combine ratios (Mc/Mb,Ic/Ib) and pushover analysis is performed on each ratio’s. The result of the investigation highlighted on the objective that is to find exact SCWB ratio value considering the parameter like target displacement, ductility ratio, hinge response etc.

Analysis of Multi-Storied Building with Prestressed Beam using ETABS

Concrete is good in compression and weak in tension and the steel is strong in tension. So the use of reinforced concrete to resist compression and to hold bars in position and to the steel resist tension. In India RCC structures are commonly used in residential as well as business buildings. Nowadays the Post Tensioning method is widely used due to its advantages. Post tensioning is a form of prestressing, that means the steel is stressed before the concrete has to support the service loads. In this paper is exposed to the assessment of execution of Reinforced concrete beam (RCC beam) and Post-Tensioning beam (PT beam) multistoried building structure framework with seismic load using ETABS software. And also evaluate the performance of PT beam under different seismic zone (zone I, zone II) evaluate the performance of PT beam under soil type (medium soil) and compare the performance of RCC deep beam and PT beam with multistory building system with seismic loading performance.

Analysis of multi-story buildings with hybrid shear wall: steel bracing structural system

Numerous studies were contemplated on the structures with distinctive structural configuration and ample amount of work is currently being performed through the investigation of the response of individual behavior of shear walls and bracings by varying configurations and their material properties. Seismic design philosophies had mentioned firmly that a structure must accomplish Life Safety and Performance Level for both reinforced concrete and steel structures. This study is anchored on prevailing lateral load resisting system which is virtuous but not adequate to retain vigorous ground motion or acceleration. To overwhelm this problem, an attempt was made to familiarize a new lateral load resisting system formulated by the amalgamation of two different existing lateral load resisting systems, specifically shear walls and bracings. The hybrid structural system embraces two distinctive lateral load resisting techniques, shear walls, and bracings for moment-resisting frame. A numerical finite element study was carried out by the linear dynamic method on the response of structure subjected to seismic condition and an optimal configuration of the different structural patterns is assured by using numerous possible patterns of a hybrid structural system using finite element-based software. The criteria contemplated for study including time period, base shear, overturning moment, story drift ratio, and story displacement are compared with different models and the optimal structure is concluded based upon the recital. The comparative results revealed that there is a reduction noticed in the fundamental time period, and story displacement, where as there is negligible increment in base shear and overturning moment for the hybrid structural system as compared to other configurated models.

Seismic Analysis of Multistoried Building on Sloping Ground with Ground, Middle and Top Soft Storey

Buildings that rest on sloping ground are different from those that rest on level ground. Buildings located on sloping ground are much more prone to earthquakes because they are, in general, irregular, asymmetrical and tensional. Therefore, the movement of the ground affects them much more. Therefore, there is increased insertion of the shear wall to resist side loading. In this work, the multi-storey building G + 20 is analyzed on slopes of 0o and 24o. For the improvement and analysis of full-filled shear walls, GMT, type L and type C soft soil is used. The structure is analyzed by the response spectrum method and responses such as displacement, ground deviation, period and base slices are evaluated and compared using E-TAB software.

Linear static analysis of multi storey building with horizontally asymmetric architectures

Multi-storey reinforced concrete (RC) frames with horizontally asymmetric architecture are very common these days due to rapid urbanisation and scarcity of land. Site dimensions, architectural requirements and sometimes client requirements generally force the designer to adopt buildings with horizontally asymmetric architecture. So there is a need to study the seismic effect on buildings with horizontally asymmetric architecture. The objective of this study is to evaluate the performance of buildings with horizontally asymmetric architecture located in the city of New Delhi (Zone 4) and subjected to earthquake. Manual analysis results for a typical ten floor building were compared with those obtained by STAAD.Pro. to validate the Linear static analysis procedure of STAAD.Pro. One regular building and four irregular buildings of same base area and same spacing of columns with heights of 15 m, 30 m and 45 m are analysed and compared for this study. For 5, 10 and 15 floor RC frames considered for study, it is observed that frames with horizontally asymmetric geometry − 2 result in least vales of Axial force in columns and Bending moment in beams with respect to the regular (R) and other horizontally asymmetric geometries I1, I3 and I4.
