高层建筑施工附着升降脚手架的极限承载力(2)

Ultimate load-carrying capacities of the integral-lift scaffolds attached to tall buildings(2)

建立了附着升降脚手架各主要杆件的有限元单元刚度矩阵,在总结各类形式脚手架共性的基础上,做了进一步系统的简化和假设,形成了附着升降脚手架的承载力计算模型,给出了附着升降脚手架在其竖向荷载及竖向荷载和水平风载两种工况下的极限承载力计算方法,并基于定型化、工具化、标准化原则,建立了以脚手架构件主要尺寸变量为参数的极限承载力计算表格,可供工程人员参考使用。

For getting a reasonable upper bound prediction of the ultimate load-carrying capacities, geometric nonlinear and material nonlinear analysis both under vertical load and horizontal wind load are performed in the paper. The research provides useful guidelines for the safety design of integral-lift scaffold.
