钢框架结构的优化设计研究
|
摘要
近年来,工程结构复杂性日益增加,人们对结构的安全性和可靠性要求也日益提高,以往传统设计方法已远远不能满足要求,迫切需要一个准确性好、效率高的新的设计方法出现。各种信息集成技术、设计技术相继出现使以上要求成为可能,其中最基础的方法是有限元分析和优化设计。论文主要结合数学规划方法与有限元法,以计算机为工具,对钢框架结构的优化设计进行了研究,并提出了基于整体优化策略的非线性抗震设计,以期通过提高设计效率,实现建筑材料的合理使用和工程造价的有效降低。
In recent years,the increasing complexity of engineering structures,people safety and reliability requirements are increasing structures,of traditional design methods can not meet the requirements,the urgent need for an accurate,high efficiency of the new design method appears.Integration of various information technology,design technology to make the above requirements have emerged as possible,which is the most basic method of finite element analysis and design optimization.In this paper,based on mathematical programming method and finite element method to the computer as a tool to optimize the design of steel frame structures have been studied and proposed nonlinear global optimization strategy based seismic design,in order to improve the design through efficiency,building materials rational use and reduce the project cost.
