【摘要】 提出了钢筋混凝土单筋梁优化设计方法。该法以梁单位长度的造价为目标函数 ;以规范对单筋梁的正、斜截面强度及构造要求为约束条件 ;以梁截面尺寸 ,主筋直径、根数 ,箍筋直径、间距等为设计变量。最后对各分项的经济性做了分析比较更多还原

【Abstract】 In this paper,an optimization design method of reinforced concrete beam with single reinforcement is presented.The objective function is the cost of beam per meter.The constraint conditions are the strength of beam′s normal section and inclined section,construction demands in the design code.The design varables are the size of beam section,diameter and quantity of reinforcement,diameter and space of hoop.The costs of various items are analysed.更多还原
