摘　　要：扣件式钢管脚手架是目前国内建筑施工中应用最为广泛的脚手架形式。本文利用SAP 2000软件分别建立了铰接节点和框架节点的脚手架门洞模型,对两种不同脚手架门洞构造(上升斜杆-平行弦杆桁架构造和门式桥架构造)的受力特点进行了分析,并提出了常用构造方案中脚手架门洞处杆件轴力的优化设计方法。Steel tubular scaffold with couplers is the most widely used scaffold in Chinese construction industry. This paper used SAP 2000 to establish the models of scaffolding with doorway of hinged joint and frame joint and analyzed the stress characteristics of two different kinds of structures of scaffolding with doorway （ structure of rise diagonal-parallel chord lever and door type of crane span structure ）. It proposed a design method of the axial force of members near the doorway of scaffolding in the situation of common structural project.
