Seismic Risk Assessment of Structures Using Multiple Stripe Analysis
The implementation of seismic risk assessment of existing structures is necessitated for practical engineers to select the retrofitting strategies. The reliability based approaches are proposed to investigate the behaviour of structures subjected to ground excitation and encouraging evaluation results of various typologies of structures have been obtained exploiting such methodologies. The decision regarding the retrofitting strategies that will rehabilitate the flaws of the structure under prescribed ground motions that have high probability of occurrences at the scenario can be made. This paper addresses the generation of hazard curve by probabilistic seismic hazard analysis from the seismological point of view. The multiple stripe analysis, as one of typical probabilistic based assessment procedures, will be utilized to evaluate the structural seismic fragility. The seismic risk can be estimated based on the numerically integrating the fragility function with the hazard curve.
