Abstract：The research objective is to design and construct an improved method for damage reliability analysis of concrete gravity dam. Firstly, we use pseudo excitation method and Mazar damage model to analyze how to calculate damage expected value and variance excited by random earthquake loading and deterministic static load in the initial iterative step. Moreover, based on perturbation theory, we analyze probability density evolution process in other iterative steps. Finally, we give a test example to verify and analyze the convergence and stability of this method.
