半刚性柱脚连接门式刚架的几何非线性分析

Semi Rigid Column Base Joint Geometric Nonlinear Analysis of Portal Frame

随着我国工程建设进入精细化设计与施工的阶段,新型材料的研发与应用越来越迅速,轻型的钢结构建筑也开始广泛出现,尤其是用于厂房的轻型门式刚架,由于其结构自重轻,施工简便,造价低,受到广泛的欢迎,逐渐取代钢筋混凝土的排架。随着工程量的增加,门式刚架的造价进一步降低,更加具有广泛的应用前景。论文在这样的社会和行业背景下开始了本课题的研究,专门讨论门式刚架,重点讨论半刚性柱脚连接的门式刚架的受力问题。希望通过本文,能够将半刚性柱脚连接门式刚架的基本受力问题分析清晰。

Along with our country construction into the design and construction of the fine stage,the development and application of new materials more and more quickly,the light steel structure building also became popular,especially for the light portal frame building,because of its lightweight structure,simple construction,low cost advantages have been widely welcomed,therefore replace bent reinforced concrete.With the increase of quantities of the portal frame to further reduce the cost,which has wide prospect in practice,this paper started the research in such a society and industry background,this paper discusses the portal frame,focusing on the stress problem of door type semi rigid column base connection frame.I hope this paper can be semi rigid column base is connected with the basic force of the portal frame clear analysis.
