[摘要] 為解決某高聳結(jié)構(gòu)的優(yōu)化設(shè)計(jì)問題，基于參數(shù)化設(shè)計(jì)思想和有限元方法，在論述風(fēng)荷載和地震荷載的有限元處理方法，以及分別分析風(fēng)荷載和地震荷載作用下該高聳結(jié)構(gòu)變形和應(yīng)力分布的基礎(chǔ)上，結(jié)合APDL語言和大型通用有限元分析軟件ANSYS中的Design Opt工具進(jìn)行優(yōu)化設(shè)計(jì)，合理確定各梁、桿單元的橫截面尺寸。該方法避免了傳統(tǒng)設(shè)計(jì)方法中繁雜的手工計(jì)算與驗(yàn)證，提高了設(shè)計(jì)精度和效率。

Abstract: In order to solve the problem of optimal design about a high-rise structure, the deformation and stress distribution ofa high-rise structure under the effect of wind and seismic load, whose finite element techniques was discussed, was solved respectively based on parametric design and finite element method. Based on APDL language and Design Opt tools in large general-purpose finite element analysis software ANSYS, the optimization of the structure was executed, and then the cross sectional size of elements about beams and bars was obtained. The method avoids the complex manual calculation and verification in traditional methods and improves design accuracy and efficiency.
