半刚性连接节点刚度对门式刚架结构弹性分析影响研究

Study on the Influence of Rotational Stiffness of Semi-rigid Connection to Elastic Structural Analysis of Gabled Frame

传统的分析和设计方法都将梁柱连接节点处理成理想的刚接或铰接,然而实际工程中的连接节点的受力性能总是介于这两者之间,属于半刚性连接。本文研究半刚性连接的节点转动刚度对门式刚架内力分布和结构位移的影响,并得到了一些有益结论。

For traditional analysis and design method,the beam-to-column connections are often treated as either rigid or hinged.But the actual mechanical property of the joint in practical engineering is in between the two situations,namely semi-rigid connection.In this paper,the affect of rotational stiffness of semi-rigid connection to the internal force and displacement of gabled frames are discussed,and some useful conclusions are found out.
