摘要
本文提出了在板梁结构设计中采用部分预应力计算理论与工程结构优化分析理论相结合方法进行结构设计,以构件满足各受力阶段强度、刚度要求为边界约束条件;以单片梁总造价为目标函数,通过求解多元非线性方程组,进而得到理论结构优化计算结果。
This paper uses the method that combining portion prestress computer theory with engineering structure optimum analyses to design structure. The boundary constrained condition is that component should meet the demand of stress intention and stiffness. Objective function is single beam cost and result is computed by dispelling multipleunit system of nonlinearly equations.
