Effect of Shear Wall on Seismic Performance of RC Open Ground Storey Frame Building

Abstract

The Open Ground Storey buildings are very commonly found in India due to provision for very much needed parking space in urban areas. However, seismic performance of this type of buildings is found to be consistently poor as demonstrated by the past earthquakes. Some of the literatures indicate that use of shear walls may enhance the performance of this kind of buildings without obstructing the free movement of vehicles in the parking lot. The present study is an attempt in this direction to study the performance of Open Ground Storey buildings strengthened with shear walls in a bay or two. In addition to that, the study considers a different scenarios of Open Ground storey buildings strengthened by applying various schemes of multiplication factors in line with the approach proposed by IS 1893 (2002) for the comparison purpose. Study shows that the shear walls significantly increases the base shear capacity of OGS buildings however the comparative cost is slightly on the higher side.
