Abstract: Shear walls play a key role in the lateral-load resistance process in high-rise buildings, as well as resisting the lateral loads generated by seismic forces. This paper examines the effect of shear walls in rectangular, L, and U type and their locations in RC building under seismic excitation. Seismic impact is primarily concerned with structural protection, particularly during the earthquake and also with high-rise buildings, ensuring adequate lateral rigidity to withstand seismic loads is very critical. Rectangular, L and U shaped shear walls was analyzed and compared at various location using non-linear analysis. For analysis three models were considered with various above said shapes at different locations of high rise buildings in high seismic regions of Ethiopia. The structure’s seismic capacity and demand were analyzed using non-linear pushover analysis based on displacement. Regular in plane and elevation building for this investigation G+7 was targeted to estimate the structure’s seismic response and resistance capacity Non-linear dynamic time-history analysis was performed for comparison, by applying 30 artificially generated ground motion for all sample buildings. The capacity curves of the structures, as derived by pushover analysis were compared for buildings with rectangular, L and U shape shear walls using Seismo-Struct software. Also, the performance levels of structures are estimated and compared using Seismo-Struct software to perform non-linear dynamic time-history analysis.
