PROBABILISTIC SEISMIC DEMAND ANALYSIS: SPECTRUM MATCHING AND DESIGN.

The current state and trend of Earthquake Engineering practice calls for better understanding of structural nonlinear response due to strong ground motion excitation. The present study deals with issues on such structural-systems understanding, in light of recent developments in Probabilistic Seismic Demand Analysis (PSDA), which is a practical interface between the elastic and inelastic representations of structural behavior and ground motion hazard, in a probabilistic framework. One part of this study deals with requirements of PSDA in terms of structural response representation: efficient and accurate estimations of response. Ground motion response spectral shape is studied and is recognized as having an…
