摘　　要：针对钢筋混凝土结构承载力和工程造价要求,采用罚函数法,对钢筋混凝土梁的截面尺寸和钢筋的用量进行优化设计.提出了采用矩阵实验室(MATLAB)优化工具箱的方法,对C20到C40混凝土和HRB335,HRB400钢筋进行多种组合.结果显示在满足承载力要求及规范所规定的构造要求条件下,选用C35和HRB400为最经济的设计方案.We used the penalty function to optimize the design of reinforced concrete based on the bearing capacity of reinforced concrete structures and construction cost requirements,and optimized the design of reinforced concrete beam section and the amount of reinforcement.The method of optimization design was proposed by using the method of Matrix Laboratory optimization toolbox.We analyzed a variety of combinations of C20 to C40 concrete and HRB335,HRB400 reinforcing steel bar.The results show that the choice of C35 concrete and HRB400 reinforcing steel bar can meet the bearing capacity requirement and standard requirement,which is the most economic plan.
