Failure credibility is popular in measuring safety degree of structure under fuzzy uncertainty, but the heavy computational cost is still a challenge in estimating the failure credibility. To alleviate this issue, an iterative method combining adapti

Global sensitivity analysis (GSA) is useful to recognize important inputs for assigning priority and unimportant inputs for simplifying models by exploring whole distribution ranges. Meanwhile, regional sensitivity analysis (RSA) is also studied for

Failure credibility is popular in measuring safety degree of structure under fuzzy uncertainty due to its excellent property of self-duality. Existing methods for estimating failure credibility can be mainly divided into two categories, i.e., the sim

Fuzzy uncertainty (FU) exists widely in engineering applications, but there lack design optimization methods under FU, thus a credibility-based design optimization (CBDO) is focused to obtain the safety design under FU in this paper. Firstly, the con

In order to make a good compromise of cost and safety with small data in the early structural design stage, a practical decoupled credibility-based design optimization method is developed in the presence of fuzzy uncertainty. In the proposed approach

In order to measure structural safety with fuzzy uncertainty, a new root finding method of failure credibility is presented by taking advantage of the simple relation on input and output credibility inverse distributions. A brief introduction is give
