摘要
以梯形钢屋架为优化实例,采用非线性规划法和钢结构设计的基本理论,结合MATLAB 7.0的数据拟合功能,建立了梯形钢屋架优化设计的数学模型,采用LINGO 9.0程序对模型进行了求解,并通过对求解结果的再分析验证了模型的可行性,分析表明:采用非线性规划对钢屋架优化设计能满足设计要求,同时能取得较好的优化设计效果和经济效益.
A trapezoid steel truss optimization example is given, by using nonlinear programming and the basic theory of steel structure design. We take MATLAB7.0 to establish a nonlinear programming mathematic model, which be solved by LINGO9.0 and give the optimal cross section of members. Then we check the section and ensure it to meet the standard requirements. Research conclusion and the research method provide a reference for the similar design.
