门式脚手架的搭设构造及设计计算

LINKING FORMS AND THEIR DESIGN CALCULATION OF DOOR-TYPE SCAFFOLD

文章运用弹性稳定理论的有限元法．探讨了门式钢管脚手架各种搭设状态下的实际受力性能，分析了影响脚手架承载力的各主要因素．文中还提出了承受非比例荷载的结构稳定计算新方法。通过计算表明，所提出的计算方法对门式钢管脚手架的设计计算有实用价值。

In this paper,the finite element method for elastic stable theory is ueed to deal with the practical laed-bearing properties of door-type steel pipe scaffold linking in different way and analyze main factors influencing the load bearing ability of scaffold. A calculating method is also put forward for non-proportional load bearing structures to calculate their stability.It is shown through calculation that the method proposed in the paper has great practical value for the design and calculation of door-type steel pipe scaffolds.
