Abstract

Behavior of building under earthquake loading is complex in nature. It depends on mass, timeperiod, stiffness and horizontal as well as vertical configuration of structure. In past it is observed that buildings having certain vertical configuration seemed to be more prone to damage in earthquake than others, irrespective of which construction material or structural systems had been used. Irregularities in vertical configuration (Soft storey) tend to create abrupt changes in strength or stiffness that may concentrate forces in an undesirable way. So, although the size of the overall force that building must withstand is determined by the Newton's second law of motion, the way in which this is distributed and concentrated, is determined by its vertical & horizontal configuration. However, shear wall placement and location play an important role in resisting the horizontal thrust due to earthquake and wind. Present study carried on eleven storied reinforced building located at various seismic zones and parameter are considered as base shear, stiffness, time period, storey displacement, drift. For evaluating the results ETABs analysis software is used.
