| Abstract: |
| Reliability mapping functions are constructed based on the theory of structural reliability analysis,the double-loop for reliability-based structural optimization (RBSO) can be transformed into the single-loop by using reliability mapping functions.The reliability mapping function can solve the problem that RBSO is unfavorable for engineering application because of the large number of calculations.The reliability mapping function has a clear theoretical basis,and can ensure that its application to RBSO is feasible.To improve the evaluation accuracy of failure probability,an improved response surface method (RSM) is proposed based on the design point,and the improved RSM is used to obtain reliability mapping functions.Examples are shown that the proposed method has high accuracy and efficiency,the number of performance function evaluation of the proposed method is less than that of other methods,and can obtain satisfactory optimization results. |
