摘　　要：剪刀撑能够提高满堂扣件式脚手架的整体稳定性,加强脚手架纵横杆、立杆等部位的连接,在传递荷载等方面发挥着重要的作用。通过MIDAS/GEN有限元分析软件建立3×3跨的满堂式扣件脚手架模型,模拟在不同的剪刀撑设置情况下及相同荷载作用下,研究脚手架立杆应力及架体位移的变化规律。其结果可作为研究满堂扣件式脚手架应力传递以及脚手架实际工程中水平、斜向剪刀撑设置等方面提供相应的借鉴和参考。Bridging can improve the overall stability of a bunch of the fastener full-hall formwork scaffold,it can strengthen the scaffold connection in areas such as the vertical and horizontal pole and play an important role in load transferring. In this paper,set up a 3x3 fastener full-hall formwork scaffold model by using MIDAS / GEN software to get the changing rules of stress and displacements of the scaffolding upright stanchion in different bridging circumstances and the same loads. The results can be used as a reference for studying the rules of stress transferring of the fastener full-hall formwork scaffold in practical engineering to make the correct position of the horizontal and sloping diagonal bracing.

关 键 词：满堂扣件式脚手架 剪刀撑 应力 位移 刚性模型
