ABSTRACT

System scaffolds used in construction sites have the reused characteristic that members are used repeatedly without discarding it in terms of price, environment, and recycling. It is known that the performance of reused products could be decreased compared to the nominal allowable stress due to ‘reuse of members’ and ‘residual stress by manufacturing method’. Therefore, there is a possibility that there is a difference between the structural safety intended by the designer and that of the reused members to be installed. In this study, the performance test report of the scaffold vertical members of the reused scaffold stored and managed at the construction site in Korea was collected, and the strength reduction was analyzed considering the buckling curve specified in the design standard (Eurocode 3).
