Study on Safety of the Fastener Tubular Steel Scaffolding

Abstract

Based on analysis of five different conditions’ full scale model tests of the fastener tubular steel scaffolding, the paper introduces that notional lateral loads can imitate the effect which generalized imperfections of the falsework(initial imperfections, node semi-rigid and so on) give the bracket’s stability capacity. According to the finite element software ANSYS, the falseworks’ stability capacities of different conditions have been imitated and analysed, Analysis results compare with test results. The final result indicates that it is reasonable that notional lateral loads in certain scope can imitate generalized initial imperfection. Research results can be used for on-site t technical personnels’ design and safety control.

Scaffold research — A review

“…Recent research in China has been undertaken on theoretical and experimental models of tube-and-fitting scaffolds. Hu et al [79][80][81] undertook experiments on scaffold assemblies and showed that when the imperfections in the scaffold were correctly modeled that correspondence was made with analytical models. Li et al [82] developed a semiempirical design tool for the analysis of scaffolds and compared the results with a finite element program with good correlation.…”
