钢筋混凝土框架结构整体优化设计

Optimum Design of Reinforced Concrete Frameworks

探讨了钢筋混凝土框架结构的整体优化设计问题。以钢筋混凝土框架总造价为目标函数，梁、柱截面尺寸和配筋量为设计参数，规范规定为约束条件，采用迭代算法，并进行灵敏度分析，以寻求最优解。实例表明该方法是有效的。

An efficient iterative algorithm based on optimal criteria for the optimal design of reinforced concrete building frameworks has be presented. The optimization problem is minimizing the cost of concrete,steel,and framework subject to constrains on strength and stiffness. The width, depth,and longitudinal reinforcement of member sections are taken as the design satiables.The sire rigth constrains for the design are formulated using both member capacity sensitivites and structure response sensitvites.A reinforced concrete framework example is presented to illustrate the effectiveness of the design optimization method.
