摘要
提出了钢筋混凝土偏心受压柱全约束条件下的离散变量优化设计模型,设计变量取截面尺寸(b×h)、纵向钢筋直径及根数、箍筋直径及间距,以规范对钢筋混凝土柱抗压、抗剪强度要求,最小配筋率要求,稳定性要求,抗震设防要求等建立约束条件,以柱的全部材料造价为目标函数。通过实例计算表明,该方法对指导钢筋混凝土偏心受压柱的设计,节约造价是很有价值的。
The discrete variables optimum design model is proposed for the eccentric compressive reinforced concrete column with full constraints. The design variables include the dimension of the column section(b×h),the diameter and number of lognitudinal reinforcing bar, the diameter and span of stirrup. The constraint conditions are all design requirements in the code, such as the requirements of compressive strength and shearing strength, the minimum ratio of reinforcement , vertical stability, earthquake resistance, and so on. The objective function is the cost of the entire material used to construct the column. With a practical example, it can be shown that the proposed model is valuable for design of the eccentric compressive reinforced concrete column and reduction of the cost.
