任意分布参数的梁结构可靠性优化设计

Reliability-based Optimal Design of a Beam Structure with Arbitrary Distribution Parameters

在可靠性设计理论和优化设计方法的基础上,讨论了任意分布参数的梁结构可靠性优化设计问题,提出了任意分布参数的梁结构可靠性优化设计的计算方法。在基本随机参数的前四阶矩已知的情况下,通过计算机程序可以实现任意分布参数的梁结构可靠性优化设计,迅速准确地得到任意分布参数的梁结构可靠性优化设计信息。

Using the reliability-based design theory and the optimal design method, we propose a numerical method for calculating the reliability-based optimal design of a beam structure with arbitrary distribution parameters. Under the condition that the first four-order moment of basic random parameters is known, we use computer programs to do the reliability-based optimal design of the beam structure with the arbitray distribution probability and obtain quickly and accurately the information on the optimal design. A numerical instance shows that the numerical method is practical and effective for the reliability-based optimal design with arbitrary distribution parameters.
