地震荷载作用下框架结构的优化设计
|
摘要
将多目标和多级优化设计理论应用于框架结构的设计中,把整个优化过程分为系统优化和单元优化,以结构的应变能最大和结构造价最低两个目标函数为优化目标进行优化设计,按照现行的相关规范建立数学模型,并通过钢框架结构的计算实例结果表明提出的理论和计算方法是合理的。
This article applies the multi-objectives and the multistage optimized design theory in the portal frame construction design,divides into the entire optimized process the system optimization and the unit optimizes,is biggest take the structure strain energy and the structure construction cost lowest two objective function carries on the optimized design as the optimized goal,according to the present related standard establishment mathematical model,and through the steel portal frame construction computation example result indicated this article proposed the theory and the computational method are reasonable.
