The Integrated Soil-Structure Fragility Analysis (ISSFA) method, presented in this paper, is intended to utilize the recently available computation power with the established analysis techniques to develop a more reliable foundation for the performance based seismic design of buildings with significant Soil-Structure Interaction (SSI) effects. The input data for ISSFA are the site specific seismic hazard curve and rock motions at different hazard levels and site specific soil profiles as well as the structural model of the considered Systems, Structures, and Components (SSC).

The results are the fragility functions for specified limit states that in conjunction with the seismic hazard curve yield the annual probability of failure (1- target performance) for the SSC. In this paper, the developed Integrated Soil-Structure Fragility Analysis (ISSFA) methodology is outlined and discussed. Important aspects of the method such as selection of ground motion hazard parameter, propagation of low frequency (LF) and high-frequency (HF) seismic events, and importance of SSI effects are discussed for a representative example structure.
