扣件式钢管脚手架以其受力合理、空间结构整体性好等特点在高层建筑施工中得到广泛应用。对高度不大的架子,以经验估测其承载力,一般还能满足施工要求,但对高度较大的架子,通过结构计算来保证其承载力不出问题,已成必然。为不失一般性,本文先从薄壁构件弯扭基本方 The fastener type steel pipe scaffold is widely used in the construction of high-rise buildings because of its reasonable force and good spatial structure. For shelves with little height, the bearing capacity can be estimated by experience. Generally, it can meet the construction requirements. However, it is inevitable for the shelf with a larger height to guarantee its bearing capacity through structural calculation. In order to not lose the generality, this article first from the thin-walled members
