Abstract

The G+20 multi storey irregular building is taken for present study. This building is modeled and analyzed by using ETABS V9.7.4. Assuming the material property as linear and nonlinear. The performance of the building is studied by comparing the base shear, displacement, storey drift in different analysis. Multi-storey buildings with open (soft) ground floor are inherently vulnerable to collapse due to earthquake load, even then their construction is still widespread in the developing nations. An investigation has been performed to study the behavior of the columns at ground level of multi-storey buildings with soft ground floor as satellite bus stop and moment transfer beams in all storey subjected to earthquake loading. The structural action of masonry infill panels of upper floors has also been taken into account by modeling them as diagonal struts. Shear wall is one of the most commonly used lateral load resisting in high rise building. In this study building is modeled with different shapes of shear wall with top and bottom soft storey.
