SEISMIC RESPONSE OF EXISTING RC BUILDING UNDER REVISED SEISMIC ZONE CLASSIFICATION USING PUSHOVER ANALYSIS

Existing Reinforced Concrete (RC) buildings constructed before two decades typically have the design details which are considered to be highly inadequate under the present revised seismic code of practice. Many of these structures have suf fered significant structural damage during recent earthquakes. Significant research effort has been devoted to the development of behavioral models and modeling techniques to predict the behavior of these buildings. However there are no models that have been shown to predict observed response with a high level of accuracy and precision. In this paper, a seven storey RC building is considered to investigate the structural seismic response. This RC building is analysed and designed for the gravity and lateral loads using the codal provisions followed a decade ago (previous version of the code).
