Abstract

Abstract

As a major international event， the Beijing Winter Olympics used a large number of scaffolding for the construction of temporary stands or stages. The temporary stand support frame with plug-in joints was taken as the research object. A 2×2 full-scale model was designed and manufactured， and unidirectional horizontal loading tests were conducted to investigate its slip modes， displacement response， and strain distribution under no load， 0.5 kN/m²， 2.0 kN/m²， and 3.5 kN/m² conditions. The load-displacement curve was plotted to determine the structural slip load. For experimental comparison， wind loads corresponding to Level 10-12 wind forces in the competition zone were selected to verify the safety and stability of the frame structure in practical engineering applications. An 8×2 analytical model was established using SAP2000 to evaluate the mechanical properties indicators such as modal characteristics， anti-overturning stability， and stress ratios of the overall structure.The results showed that the frame structure exhibited excellent anti-slip stability， and most of the members remained in an elastic stress state during the test. Since the external load applied in the test was much higher than the actual wind load， the structural system possessed a large safety reserve. This study can provide technical support and reference for the practical application of plug-in scaffold support frames.
