在建筑施工中,脚手架倒塌事故时有发生,造成脚手架倒塌事故的原因主要是脚手架失稳。因忽视结构稳定性问题而发生的其它建筑事故也不少,由此造成的经济损失和人员伤亡也比较严重。本文主要讨论脚手架失稳倒塌问题,也可供其它相似问题借鉴。脚手架失稳是一种整体失稳,但失稳的原 In construction, the collapse of scaffolding accidents have occurred, causing the collapse of the scaffolding is mainly due to the failure of scaffolding. There are also many other construction accidents that have taken place due to neglect of structural stability issues, resulting in serious economic losses and casualties. This article mainly discusses the problem of collapse and collapse of scaffolding, but also for reference to other similar problems. Scaffolding instability is a kind of overall instability, but instability of the original
