摘要
本文对门式钢管脚手架建立三维空间力学模型，考虑连接节点的半刚性，进行了二阶弹性稳定分析．通过对门式脚手架的试验研究，深入探讨了不同搭设条件对门式钢管脚手架稳定极限承载力的影响，并取得定量，定性结果．本课题研究成果为编制门式钢管脚手架施工规范提供科学依据．
Based on a three-dimensional space mechanics model,this paper discusses the elastic stability of frame scaffold,concerning the semirigid joints of the scaffold.With the aid of the experiment,this paper analyses in detail the collapse bearing capacity of the scaffold which is influnced by different scaffold-Installed methods.The qualitative and quantitative results are obtained.The results provide scientific basis for working out the code of using flame scaffold.
