英文摘要	A new hybrid reliability model is presented for the case that truncated probabilistic variables and non-probabilistic variables exist simultaneously in engineering. Based on the new hybrid reliability model and reliability index assessment (RIA) method, a nested loop hybrid reliability-based optimization model is also presented. Modified ST-Powell optimization algorithm with better search strategy is used to search the optimal values of design variables in the out-loop. Modified limit step length iteration algorithm, which can ensure convergence, is used to solve the new hybrid reliability index in the inner-loop. Numerical examples show that the global optimization rate of the modified ST-Powell optimization algorithm with better search strategy can be promoted significantly, and the validity of hybrid reliability-based optimization model searched by the algorithm presented in this paper is proved. The algorithm can obtain the optimal values for hybrid reliability-based optimization model with high nonlinear limit state function. The algorithm presented in this paper has a good adaptability to hybrid reliability-based optimization problems of engineering structure. 2017, Press of Chinese Journal of Aeronautics.
