| 摘 要： | 由于门式刚架梁柱截面尺寸选择的复杂性和设计变量的离散性,传统的优化方法得不到理想的优化结果。论文以《门式刚架轻型房屋钢结构技术规程》为基础,采用遗传算法,对门式刚架进行优化设计。运用MATLAB语言编制了结构优化程序,并开发了优化程序的图形用户界面。算例表明,该优化方法算法简便,编程简单,优化效果明显。优化程序的图形用户界面简洁明快,操作简单。

| Abstract: | Due to the complicacy in the selection of steel portal frame beam and column cross-sections and the discrete nature of their design variables,it is difficult to obtain satisfying results with traditional optimization methods.In this paper,the authors used MATLAB to make the structural optimization program of portal frame based on the Technical Specification for Light_Weighted Steel Portal Frames of China.The method of optimization is a discrete variable and genetic algorithms method.The examples illustrate that this method is very efficient,simple and easy to program.What's more,the GUI of optimization program is explored so that it is much easier to use optimization program. |
