在冷弯薄壁管桁轻钢体系中,墙体是一个很重要的构件,它既传递竖向荷载,同时还抵抗水平荷载。但是在以往的研究中,通常都是假定墙体中横向的横撑和竖向的轻钢柱刚接在一起,轻钢柱与地面基础也刚接在一起,并没有谈及当它们铰接时结构会怎样变化。本文利用3D3S软件分别建立了节点及支座刚(铰)接轻钢骨架墙体模型,通过分析得出节点铰接或支座铰接都会较大地降低墙体的抗侧刚度,建议在实际工程中要尽量保证节点刚接以及支座刚接。
In cold-formed thin-walled tube trusses light steel system, the wall is a very important component, which not only transmits the vertical load, but also resists the horizontal load. However, in previous studies, it was generally assumed that the horizontal cross-struts in the wall and the vertical light steel columns were just joined together, and the light steel columns were just connected to the foundation of the ground and did not mention when they were hinged How the structure will change. In this paper, the 3D3S software was used to establish the rigid-hinged light steel skeleton wall model of the joint and the bearing respectively. It is concluded that the articulation of the joint or the articulation of the bearing will greatly reduce the lateral stiffness of the wall. It is suggested that in practical engineering Try to ensure that the node just pick up and support just access.
