摘　　要：通过对"拱构型门式钢管脚手架"整体稳定承载力试验,研究其破坏模式,为建立"拱构型门式钢管脚手架"稳定承载力计算理论提供依据。重点考察了连墙件、脚手板、水平加固杆的设置及架体底部约束对整体稳定承载力的影响。并利用ANSYS软件对拱构型门式钢管脚手架整体稳定承载力进行了分析,其结果和试验吻合较好。Through the integral stability bearing capacity test on the steel tubular scaffold with arch gabled frames, the forms of failure are studied so as to provide a stability capacity method in theory. The study focuses on pieces of the wall, scaffold board, the level of the reinforcement bar settings and the constraints at the bottom of frame body, which are how to affect the integral stability bearing capacity. Meanwhile, the integral stability of the steel tubular scaffold with arch gabled frames is analyzed by ANSYS, the results prove to be in good agreement with the test.
