Efficacy of Importance Factor in Seismic Design of Indian Buildings

Abstract:

At present, seismic load evaluation for design of Indian buildings are carried out using Indian seismic code. In which, building Time period, Response Reduction factor and Importance factor alters design base shear majorly. Currently IS code defines Importance factor differently as “1” for general buildings and “1.5” for public buildings. This factor makes public buildings as heavier sections as it increases design base shear. However there are no evidence that, how this importance factor affects/alters/improves the seismic behavior of buildings. In this present study, four storey RC frames are designed with different importance factors. Pushover analyses are carried out to find its effects on over strength factor and response reduction factor.
