Dynamic Analysis of a G+13 Story RCC Building Using Shear Wall in Three Different Locations on Various Seismic Zones

Authors

Abstract

Currently, Seismic impacts are a very serious concern when designing multi-storied reinforced concrete structures. Seismic tremors have occurred in numerous parts of the globe. High-rise structures should have proper stiffness to resist lateral loads caused by Earthquakes and Winds. Consequently, Engineers are extremely concerned about finding suitable solutions that will allow structures to survive without major damage. Shear walls are structural members that are designed to carry earthquake loads and oppose lateral loads significantly. They are a good choice to increase the stiffness of high-rise structures. This paper aims to use shear walls in various locations of a G+13 multi-storied residential building and to determine the best shear wall placement in high slender buildings by analyzing story displacement, story drift, base shear, and the fundamental time period in various seismic zones according to IS 1893:2016. Three models are prepared and compared under different seismic zones. Shear walls are at the core of the building, and shear walls are at the four corners of the building, which is a combination of both. Our study's goal is to test a structure's ability to bear lateral load applied to it according to the Code and also when it exceeds the limit of allowable deformation. The prepared model for this experimentation is considered to be located on medium soil, and wind velocity is high, like 148mph. The experiment concluded that building with a shear wall combination of both core and corner will show better results in resisting lateral forces, though the combination isn’t enough to help withstand the high slender structure against very powerful earthquake attacks like Zone-V.
