| 摘 要： | 将建筑幕墙上经常使用的薄壁金属横梁的受力简化为薄板受力问题加以研究,利用弹性力学理论较为详细地分析了幕墙横梁的局部稳定性问题的由来及工程设计中常用的应对措施,并通过计算得出一系列控制局部稳定性指标,这些结果与行业标准基本上是一致的。本文还通过计算结果与技术规范的比较提出自己的看法,为今后修订此规范提供了思路和参考,使建筑幕墙的设计更加科学和规范化。

| Abstract: | The local stability of thin-walled metal member in building curtain wall structures and its design measures are analyzed in this paper.According to the theory of elastic buckling of sheet and the principle of edge yielding of elasto-plastic material,the controlling indexes of the local stability of this kind of members are calculated and deduced in detail.The results can be used as reference in the structural design of building curtain wall engineering. |
