Seismic Response History Analysis of RC Frame Building with Different Position of Shear Walls by using ETABS

Abstract

When building frames are subjected to lateral deflections due to earthquake loads, the resulting oscillatory movement can induce a wide range of responses in building occupants. Hence, lateral stiffness is a major consideration in the design of multi-story structures. Fortifying reinforced concrete frame structures against lateral forces can be achieved by strategically positioning shear walls. Shear walls are structural members used to resist lateral forces and gravity loads. The position and type of shear wall have a significant effect on the overall behaviour of the building structure. For effective application of the building frame, it is necessary to locate the shear wall in an ideal place and select the most suitable type. This article examines the response of buildings with different types of shear walls. Four different models are subjected to earthquake loads. In this study, a G+20 story RC Frame building was analysed using different positions of shear walls. The analysis was conducted according to the ASCE-07 2010 code using the time history analysis method in the ETABS software. The main parameters compared in this study are story displacement, base shear, story drift, and fundamental period.
