| Abstract: | Based on the high accuracy formula and PNET method, the expressions of sensitivity analysis for truss structural system reliability are derived in this paper. Computational results for some examples show that the expressions of sensitivity analysis derived by this paper are correct and effective, thus making it possible for the optimal reliability based design to be carried on with high efficiency. |
