摘　　要：在考虑扣件节点半刚性的基础上,利用通用有限元软件SAP2000建立了扣件式模板支架三维模型,分别采用了线性和非线性屈曲分析方法研究了模板支架的整体失稳形态和极限承载力,明确了模型的力学假定和分析过程,研究结果表明:扣件式钢管模板支架的有限元分析方法可以作为承载力验算的重要手段。On the basis of considering semi-rigid joints,SAP2000 is used to establish the three-dimension model of fastener-type tubular steel formwork-supports,the formwork-supports＇ buckling mode and bearing capacity are studied by using linear and nonlinear buckling analysis respectively and at the same time,the mechanical hypothesis and the analysis process of model are described in detail. The research results show that the finite element analysis of fastener-type tubular steel formwork-supports can be used as an important method for bearing capacity calculation.
