| 中文摘要: |
| 针对目前满堂扣件式钢管脚手架安全计算扣件节点普遍按刚性考虑，实际施工主要凭经验搭设，时常发脚手架坍塌等安全事故的现状，论文考虑扣件节点半刚性，通过室内试验得到在不同拧紧扭力矩值下的直角扣件转角刚度，结合某工程架体搭设高度9.2m，建立该工程满堂扣件式钢管脚手架模型，运用SAP2000有限元软件分析不同步距下对体承载力的影响，得到该工程步距1.285m最为合理。其研究方法和结论可为工程借鉴。 |

| In view of the present fastener steel tube full hall scaffold secure computing fastener nodes according to rigid consideration generally, Actual construction mainly by experience build-up, frequent safety accidents such as scaffolding collapse of the situation, the paper consider fastener of semi-rigid nodes, through indoor experiment test under different tighten torque value of right-angle fastener angle stiffness, combining with the engineering of scaffold build height 9.2 meters, set up the project of model, bearing capacity influence analysis of different lift height of fastener steel tube full hall scaffold by using SAP2000 finite element software, get the project the most reasonable lift height is equal to 1.285 meters. The research methods and conclusions can be used in engineering. |
