摘要
应用多阶段决策算子法,讨论了两种情况下桁架结构基于可靠度最优分配的优化设计:(1)在桁架结构造价给定的情况下,使结构总可靠度最大;(2)在满足结构总可靠度的情况下,使结构造价最低。文中给出了算例。
By the multistage decision operator technique,this paper successfully solves the optimization of trusses based on optimal reliability distribution under the two kinds of cases:(1)the reliability of trusses is maximized under the total construction cost is given;(2)the total cost is miximized under predetermined reliability of trusses.Numerical example is geven.
