应用理想性态空间法生成结构布局问题的原理与方法——关于结构布局问题的研究报告之二

Study on the Structural Layout,Part Ⅱ: Principle and Procedure of Generation Structural Layout by Ideal Behavior space appoach

本文提出了基于理想性态空间的布局生成法。通过对理想性态空间子空间——等应力空间的分析,得出了理想等应力空间的特性,以及结构性能与整体参数的关系,通过对等应力空间与满应力空间的比较,得出了整体参数与理想性态空间的选择依据,所提出的理想性态空间的布局生成法,为设计者设计结构布局提供了较为充分的选择余地。

A method for structural layout design on the basis of ideal behavior space concept is presented in the paper. From the analysis of the subspace of the ideal behavior space,that is iso -stress space,characterics of iso -stress space and the'link between structural performances and global parameters can be obtained. Criteria for selecting global parameters and ideal behavior space are established by the comparison between results from iso -stress space and full - stress space. The presented method is able to generate sufficient number of alternatives of structural layouts from which a designer can choose.
