Abstract： Considering the uncertainties of practical civil engineering structures, the Neural Network Response Surface Method optimized by Genetic Optimization Algorithm has been proposed to calculate the dynamic reliability of stoch- astic structure with TMD and MTMD. This method has both of the advantages of Neural Network Response Surface Method and the global search of GA, which can approach to optimum solution accurately of the performance function. And the iteration steps of JC method can be reduced effectively. The results of instance show that this method is effec- tive and accurate. For the stochastic structure the MTMD can greatly improve the dynamic reliability than TMD.
