-
摘要: 研究了张拉整体结构的预应力优化设计问题。采用奇异值分解法计算结构的自应力模态,以自应力模态组合系数和构件截面面积为设计变量,建立了优化设计的数学模型,提出了求解该问题的序列两级算法,算例表明了该方法的有效性和正确性。Abstract: The optimum design of prestress of a tensioned integral structure is studied. The states of self-stress are obtained by employing the method of singular value decomposition. The combination coefficients of self-stress states and cross-sectional areas of members are taken as the design variables. The mathematical model of optimization design is established and a sequential two-step algorithm is presented. Numerical example is provided to illustrate feasibility and correctness of the method.
