The optimal model of truss structure is established, in which the cross sectional areas of bar are taken as design variables, the structure weight is taken as objective function. in the process, the reliability of structural displacement and bar stress and the fundamental frequency are taken as constraint functions. from the engineering practice, all the reliability constraints, which are implicit generally with the design variables, are equalized and transferred to the conventional explicit constraints
本文將主要考慮桁架結構的優化問題，首先建立數學模型，即以桁架的橫截面積為設計變量、以重量最小為優化目標，位移、應力等可靠性及基頻為約束條件；最後，從工程實際出發，對結構系統的可靠性隱形約束進行等價顯化處理，使之轉化為常規的橫截面積優化問題。 -
