摘要
U型钢可缩性支架的承载能力主要取决于支架本身整体稳定性。讨论了考虑U型钢可缩性支架稳定性的承载能力问题,尤其对支架搭接部分对稳定性的影响进行了充分的研究,并得到一些重要的结论。
The load-bearing capacity of the U-steel yieldable support is investigated in view of its stability,and the influence of support overlap parts is studied on stability. Some important conclusions are obtained.
