Non-Classical Probability Seismic Reliability Based on Pushover Analysis

Abstract

In this paper, the probabilistic model is used to quantify the uncertainty of structural resistance, and the convex model is used to quantify the seismic uncertainty. The distribution parameters for the probabilistic model, together with the interval range for the convex model, are obtained through pushover analysis. Two-level function equation method is employed to calculate the seismic reliability of the structure. Case study shows that compared with the classical probability method, the proposed method is more simple and reasonable for seismic reliability analysis.
