Comparative Study on Seismic Analysis of 15-Storey Building for Different Positions of Shear Wall by Using BNBC 2020

Due to the geological formation of Bangladesh, it is showing the threat of earthquakes. As the number of high-rise buildings is increasing daily, there is an urgent need to design structures considering seismic loading. During earthquakes, structures are subjected to lateral displacement. Most reinforced concrete structures are designed to resist gravity loads, but they neglect the effect of lateral forces arising due to earthquakes. Shear walls are added to the building's interior as well as exterior to provide more strength and stiffness to the building. The studies have been carried out using CSI ETABS (v 16.2.1) software, and the model was developed using Finite Element Method (FEM), the model analysis was done by using Equivalent Static Analysis (ESA). The building under analysis consists of 15 floors. The building is located in Bangladesh's seismic zone – III (Bogura). After the study, various parameters like maximum lateral displacement, storey drift, storey shear, and storey stiffness were compared to find the suitable position of the shear wall.
