混凝土框架结构截面优化

摘要

从设计变量、目标函数、约束条件三方面，提出了考虑造价和延性的框架结构多目标优化数学模型，指出该数学模型的目标函数严格基于力学与混凝土理论，约束条件依规范设定，具有精确可靠性。%From the design variation,objective function,and constraint conditions,the paper points out the multiple optimal mathematic models with the consideration of cost and ductility,and points out the objective function of the mathematic model can be designed for the dynamics and concrete theoretic constraint conditions,so it has accurate reliability.
