METHOD OF THE SEISMIC FAILURE PROBABILITY EVALUATION OF THE STRUCTURE CONSIDERING MULTIPLE FAILURE MODES

Abstract

 In this paper, we propose the method to evaluate the failure probability under seismic motion of the structure considering multiple failure modes. In proposed method, the failure probability evaluation factor is unified, and it is possible to find the failure probability by integration of one parameter. In the calculation result, it is verified that the failure probability by proposed method is greater than the failure probability of each failure mode, and less than the sum event probability assumed that each failure mode is stochastically independent.
