摘要

摘要: 北京冬奥会作为大型国际性赛事，采用了大量脚手架用于临时看台或舞台的搭建。以插销式脚手架临时看台支承架体为研究对象，设计并制作了2×2足尺模型，通过单向水平加载研究其在上部载重为空载、0.5 kN/m²、2.0 kN/m²、3.5 kN/m²工况下的滑移模式、位移响应及应变分布，绘制荷载-位移曲线并得到结构滑移荷载；选取赛区当地10~12级风力作用作为试验对比，验证架体结构在实际工程应用时的安全性与稳定性；通过SAP 2000建立了8×2计算分析模型，分析了整体结构的模态、抗倾覆稳定性与应力比等力学性能指标。结果表明：架体结构具有良好的抗滑移稳定性，且试验过程中绝大部分杆件处于弹性受力状态，因试验施加的外荷载远高于实际的风荷载作用，故结构体系具有较大的安全储备。研究工作可为插销式脚手架支承架体的实际应用提供技术支撑与参考依据。

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.
