    In this paper, the maximum total strain energy criterion for optimal design of trusses and the realizability of joint displaclment and bar-force systems are discussed. It proves that the minimum modulus solutions of equilibrium equations of truss structure are a realizable set of bar-forces. Based on discriminating conditions of second unefficient case of the maximum total strain energy criterion, its efficacy is assured in every iteration by using the stress-symbol constraints and minimum stress constraints.Thus...

    In this paper, the maximum total strain energy criterion for optimal design of trusses and the realizability of joint displaclment and bar-force systems are discussed. It proves that the minimum modulus solutions of equilibrium equations of truss structure are a realizable set of bar-forces. Based on discriminating conditions of second unefficient case of the maximum total strain energy criterion, its efficacy is assured in every iteration by using the stress-symbol constraints and minimum stress constraints.Thus two-phase optimization method is proposed, for structural design under multiple loadings. This method is effective for the optimal design of truss-type structures with Stress, displacement and geometric constraints, and in most eases structural analyses or reanalyses can be avoided. Only a smaller-dimension linear programming has to be solved in every iteration. So a minimum-weight design or an approximate one can be more simplely and conveniently obtained.

    本文讨论了桁架优化设计的最大总应变能准则和位移、内力的可实现性,证明了最小范数内力组是可实现的。根据最大总应变能准则第二类失效的制定条件,利用应力符号约束和最小应力约束来避免优化过程中准则的失效,从而将结构设计的两相优化法推广到多工况问题。此法适用于具有应力约束、位移约束和尺寸约束的桁架结构优化设计,一般情况下不需结构的力学分析或重分析,每次迭代仅需解一个低维线性规划,因此能较简便地得到结构的最轻或近似最轻设计。
