| 摘 要： | 本文利用优化准则法解刚架结构优化设计问题,可以处理工程上常用的宽缘工字梁型剖面结构在应力、位移、板局部稳定性和几何约束条件下的最小重量设计。为保证迭代过程的收敛性质和解的可行性,建立了一种新的射线步。算例结果表明本方法是相当有效的。

| Abstract: | In this paper , an efficient optimality criterion method is developed for the mini-mum weight design of WF I-section frames with constraints on stresses, displacements, local buckling and cross-sectional dimensions. For the convergence and feasibility of solutions in iterative process, a new scaling procedure is incorporated in the algorithm, Computational results, for examples,show that the method presented in this paper performs satisfactorily. |
