摘　　要：建筑施工中扣件式钢管支模架倒塌是当前安全施工生产面临的重要问题之一。为配合《建筑施工扣件式钢管模板支架技术规程》的制订,利用有限元软件(ANSYS)建立扣件式钢管支模架结构系统的计算模型,并以此为基础对影响极限承载能力的主要参数进行灵敏度分析,从而得到相应的灵敏度曲线,为扣件式钢管支模架的安全搭建提供可靠依据。Failure of fastener-style tubular steel formwork is one of the key issues faced in safe construction at present. In order to provide the basis for the working-out Technical Rule for Steel Tubular Formwork Support with Couplers in Building Construction, a calculation model for construction system of fastener-style steel tubular formwork support was founded by means of software ＂ANSYS＂ and sensitivity analysis of main parameters that dominate the ultimate capacity was conducted. Relative sensitivity curves were obtained, which supply a reliable basis for erecting fastener-style steel tubular formwork support.
