A probabilistic approach for seismic risk assessment with uncertain input parameters Sanaie-Fard, Ali


The main objective of this thesis is the development of a procedure for analyzing the seismic reliability of a structure considering uncertainties in the factors affecting its performance. These uncertainties stem from different earthquakes records, from structural mass distributions, foundation characteristics, and the probabilistic nature of strength of materials. The method refers to building a database for the response of the structure for a range of uncertain parameters. This is then used in a reliability analysis to estimate the probability of failure of the structure in a given failure criterion. The software for the nonlinear dynamic analysis of structure was CANNY and the reliability software was RELAN.
