无比钢轻钢龙骨住宅组合墙体受剪性能

Analysis of shear resistance of websteel stud walls in residential structures

文章利用有限单元法对无比钢轻钢龙骨住宅组合墙体的受剪性能进行了分析,考虑了材料非线性和几何非线性,采用有限元方法分析了不同墙面板材料、不同墙架柱间距、不同螺钉间距等参数对组合墙体承载力的影响。结果表明:组合墙体的墙面板材料特性对组合墙体的受剪承载力影响非常大,随着墙架柱间距缩小、边缘自攻螺钉间距加密,组合墙体的受剪承载力明显提高。

This paper adopts the finite element method（FEM）to analyze the shear resistance of web-steel stud walls in residential structure. In the finite element model, material nonlinearity and geometric large deformation are considered. A detailed parametric study by FEM is carried out. The results show that material of sheathing has greater influences on the shear-resistance of walls. With the decrease of stud spacing, stud height, and screw spacing in the edge of the wall, the wall＇s shear-resistance has increased markedly.
