Reliability Calculation Based on Sensitivity Analysis
The optimization method based the sensitivity analysis compute structural reliability is proposed. At first, we analyze sensitivity. The stress differentiates with respect to a random variable may obtain the sensitivity. According to the sensitivity analysis, designer should modify data. Second, optimization model is established. At last, optimization problem is solved to obtain safety index ft. If multiple failure events occur, we also establish multiobjective optimization model and can solve it nsing multiobjective optimization method. An example validates the proposed method. Reliability calculation that does not analyze sensitivity is unreasonable.
