摘要
采用有限元分析软件 ANSYS 优化模块对多层钢框架结构梁柱截面尺寸进行优化分析,给出了优化次数与结构用钢量、截面尺寸的关系。优化成果表明,优化后的钢框架结构符合结构设计原理,与原设计方案相比,其体积、应力指标均得到了改善。
This paper adopts the finite element optimal technique in software ANSYS to design sectional dimension of multistory steel framework member and find the relation between iterative time and steel weight and sectional dimension. The results show that the optimum design scheme accords with structure design principle and the volume and the stress of structure is better compared with old design scheme.
