Comparative Study of Seismic Base Shear of Reinforced Concrete Framed Structures in Different Seismic Zone

Abstract

In the seismic design of reinforced concrete framed structure it is important to know the order of magnitude of the probable maximum base shear as related with the mass of structures. In this study, a comparison has been made between the base shear of RC frame located at various zones. For this purpose four building models are developed, corresponding to the structures constructed on rock soil of seismic zones II, III, IV and V of India (as per IS: 1893-2002). The base shear for the four models was calculated manually as well as using Staad Pro and Etabs software package and was compared with each other. When calculated manually the base shear of zone III, IV and V was1640.49, 2460.74 and 3691.12 kN respectively and it was increased up to 1.07% and 18.67% in case of Staad pro and Etabs respectively.
