扣件式钢管脚手架计算模型讨论与思考

Study on the Calculation Models of Steel Tubular Scaffold with Couplers

扣件式钢管脚手架是目前国内建筑施工中使用最广的脚手架形式。对比了钢管脚手架现有的几种计算模型,认为半刚性节点模型最能反映扣件连接的特点,但应该同时考虑对其他因素的影响,开展进行更多的钢管脚手架的稳定承载力试验,以对该计算模型进行检验和修正。

Steel tubular scaffold with couplers is the most widely used scaffold in China＇s construction industry.Based on the comparison on various existing calculation models of steel tubular scaffold with couplers,it is suggested that the semi-rigid node model is considered most adjacent to actual scaffold,taking other factors into account,and more stable load test should be carried out on steel tubular scaffold with couplers support to check and revise the calculation model.
