| 摘 要： | 冷弯薄壁型钢低层住宅房屋体系的墙体一般由墙体密立柱、墙面围护材料组成 墙面材料不仅是建筑的需要 ,同时也能在一定程度上对墙体立柱提供有效的支承作用 通过简化推导 ,建立起了考虑墙板的支承效应时墙体立柱的力学模型 ,并在弹性范围内 ,分别利用Rayleigh Ritz法推导出了墙体立柱两端简支、两端固定、一端固定一端自由和一端简支一端固定等 4种典型边界条件下墙体立柱的整体屈曲临界荷载 ,并将其转化成为常规形式的表达式 ,可供设计、研究参考 |
| 关 键 词： | 墙体立柱 冷弯薄壁型钢 支承效应 屈曲临界荷载 能量法 |

| Abstract: | The wall system of cold-formed lower house is consisted of steel studs and wallboards. The wallboards are required not only for architecture purpose, but also for providing bracing action to the wall studs. A simple model for analyzing the behavior of wall studs considering bracing effect from wall broad is presented in this paper first. And then, the buckling loads of wall studs for four typical boundary conditions which two ends simply supported, two ends built-in, one end built-in and one end free, one end built-in and one end simply supported are developed by Rayleigh-Ritz method. The equations given in this paper can be used for design and research. |
