Buckling Capacity of Socket-Template Scaffold System without X-Bracing
Publication: Journal of Performance of Constructed Facilities
Volume 34, Issue 1
Abstract
Socket-template steel scaffolds are supporting scaffolds that are commonly used in construction to support the gravity load of floor slabs. The buckling behavior of the overall scaffold is remarkably influenced by the complex mechanical behavior of socket connections. Inaccurate evaluation of the mechanical behavior of scaffolds has led to many collapse accidents. Thus, in this study, the mechanical behavior of the socket-template scaffold system was systematically investigated to clarify the buckling capacity of the scaffold, including the socket connections and overall system. Experiment and finite element analysis were adopted to identify the flexural behavior of socket connections and the buckling behavior of the entire scaffold system.
