Linear and Nonlinear Analysis of G+15 Story Building with and without Shear Wall by using Time History Analysis Method

Abstract

Abstract: This research study aims to analyze and compare the structural behavior of a G+15 story building with and without shear walls using the time history analysis method. The inclusion of shear walls in high-rise buildings has gained significant attention due to their ability to enhance structural stability and reduce lateral loads during seismic events. In this study, a linear and nonlinear analysis approach is adopted to assess the dynamic response of the building under seismic excitations. The methodology involves the creation of a three-dimensional finite element model of the G+15 story building using a commercial software package. The structural properties, including material characteristics and boundary conditions, are defined based on relevant design codes and standards. Two scenarios are considered: one with shear walls distributed strategically throughout the building, and another without any shear walls. The time history analysis is performed by subjecting the model to a set of seismic records representing different design earthquakes. The dynamic responses of the building, such as inter-story drifts, base shear, and structural displacements, are evaluated and compared between the two scenarios. The findings of this study demonstrate that the inclusion of shear walls significantly improves the seismic performance of the G+15 story building. The building with shear walls exhibits reduced inter-story drifts, lower base shear, and improved overall structural stability compared to the building without shear walls. These results highlight the importance of incorporating shear walls in the design of high-rise buildings in seismically active regions.
