摘要
以MATLAB多目标优化函数为工具,研究了不同截面钢—混凝土组合梁有效发挥抗弯承载力和降低截面尺寸的多目标优化问题。根据塑性理论,结合工程应用情况,给出了钢梁上、下翼缘宽度和厚度的优化比值并为工程设计人员提供了一种简化设计方法。
By using MATLAB multi-objective optimize function,the different sections of steel-concrete composite beams are analyzed in the multi-objective optimize method of improving the flexural capacity and decreasing the section dimensions. Combining the application in engineering and applying the inelastic theory, the optimal section dimensions and the ratio between the top flange and the low flange are derived. It will provides a brief design method for engineers.
