轻型木结构挂钩件连接节点力学性能及影响因素

挂钩件连接节点是轻型木结构中用于连接水平构件的重要连接形式之一,在工程中被广泛使用。该文根据挂钩件构造特点,选取了具有代表性的挂钩件,采用通用有限元分析软件ANSYS建立了此挂钩件节点的三维实体模型,对其在竖向荷载下的力学性能进行了模拟,并在此基础上分析了影响节点承载力和刚度的主要因素以及节点的破坏模式。

Mechanical Property and Influencing Factors of Joist Hanger Connection in Light Wood Structure

Joist hangers, as an important connection form, are widely used to connect two horizontal members in light wood structure. Based on configu-ration and construction features of joist hanger, a representative one is designed. ANSYS, Finite element analysis software, is used to set up a 3D solid model of this connection, and to analyze its mechanical properties under vertical load. Based on these results, the significant factors, influencing the bear-ing capacity and stiffness, and failure modes are analyzed.
