钢结构住宅结构体系优化设计研究
|
摘要
考虑不同抗震设防要求,以用钢量为优化目标,遵循受力合理、安全可靠原则,采用有限元分析和优化设计相结合的方法,对常见的7层钢结构住宅结构体系进行设计。根据设计结果分析比较各种结构体系在不同条件下的安全性能、抗侧向变形性能、抗震性能和用钢量的区别,得到一些有工程应用意义的结论,可供多层钢结构住宅工程设计参考。
Considering different requirement for fortification against earthquake ,the structural system analysis of steel structure residence at the story 7 is made with the optimal objective of the minimum steel weight follow the principles of reasonable and safe by the finite element analysis and optimal design method.Contrasting about the safety performance,lateral stiffness,seismic performance,the steel consumption is made out between different structure systems according design results.In the article,some significance conclusions for engineering applications can be obtained,which offer reference for the design of multi-story steel structure residence.
