高层剪力墙建筑结构的多目标优化

Multi-objective optimization for high-rise shear wall building

在高层剪力墙建筑结构设计中,随着结构构件种类和数量的增多,结构的传力路径变得越发复杂,结构设计工作中仅凭设计人员的经验通常难以获得最优方案。基于优化分析软件Isight和通用有限元软件Abaqus,通过二次开发编写脚本程序,搭建了完整的高层剪力墙建筑结构多目标优化流程,并对一工程实例进行了优化计算,为实现节约项目成本提供了可行可靠的途径。

In designing high-rise shear wall building,achieving Pareto optimization is impossible by experience of engineers due to the variety of structural elements and the complexity of force transfer.This paper has set up optimization procedures for high-rise shear wall building and implemented refining optimization for an engineering project.The optimization is based on Isight and Abaqus which is developed by Python.This paper gives a feasible and reliable method for saving cost.
