低多层半刚性连接框架节点有限元分析

Finite Element Analysis of Semi-rigid Connections in Multi-storey Frames

该文运用ABQUS有限元软件分别对提出的三种新型节点:暗牛腿连接、U型连接和工字型连接形式进行了精细化建模,分析了基于几何尺寸和材料特性半刚性连接的M-θ非线性曲线。在此基础上,提出了一种关于此类节点建议设计方法。

In this paper,the ABQUS f inite element software was adopted to propose the three emerging types of connections： Concealed coral connec-tions, U-shaped connections and I-shaped connections, with fine models established. The non-linear curve of the semi-rigid connections based on physi-cal dimension and materials＇ properties was also analyzed. Furthermore, a design method for such connections is proposed.
