Abstract
Irregularly shaped buildings have gained popularity in recent years from aesthetic requirements, limited land area, and the need for natural light and ventilation. Among these, setback buildings are a well-known type of vertical irregularity. These buildings tend to be more susceptible to seismic forces compared to regular buildings. However, by placing shear walls at suitable areas; their susceptibility can be significantly reduced. This study investigates the optimum position of shear walls in setback shape buildings. Four setback shape configurations of G+10 storeys were investigated: setback at Half, setback at two positions, setback on both sides, and setback on all four sides. ETABS analysis software was employed using Response Spectrum Method as per NBC 105:2020. The findings of this study clearly establish the optimum positions for shear walls in setback-type buildings and demonstrate easily how shear walls can simply resist storey displacement and drift when subjected to seismic loading.
