[提要] 依据《门式刚架轻型房屋钢结构技术规程》，建立了轻型房屋钢结构（简称门式刚架）离散变量优化的数学模型，应用离散复合形优化方法，在3D3S( V3.0)软件的基础上编制了门式刚架的结构优化程序。算例表明，该方法实用可靠，快捷方便，经济效益明显。
[关键词] 门式刚架 结构优化 离散变量优化Based on Technical Spec,i[ication for Steel Structure of Steel One-story Light-weight Building with Gabled Franzes, the optimization model of steel one-story light-weight building with gabled frames via discrete variables is built, and the complex method with discrete variables is improved. Optimization programming is implemented in the space steel system CAD software-3D3S. Numerical examples illustrate the method is reliable, convenient and efficient.
Keywords: portal frame structure; structural optimization; discrete variables
