- Description
- This study investigates an application of FEMA P695 (ATC-63) methodology for assessing collapse performance of reinforced concrete (RC) structures including the effect of soil-structure interaction. The new generation of performance based design approaches consider the SSI as a direct concern in order to more realistically estimate the seismic performance of structures. In response, this study investigates the SSI effects on seismic performance from within the framework of collapse performance evaluation of a medium height (eight-story) RC special moment frame structure. Comparison with similar studies on fixed-base counterparts results in prescribing conditions for how collapse evaluation should be implemented with SSI taken into account. In this paper the effect of SSI on the collapse behavior of the RC structure is illustrated by both pushover and IDA analysis in comparison with the fixed base structure.
