摘　　要：本文进行了新型整体折叠框架式帐篷结构在雪荷载和风荷载作用下的足尺静力加载试验。结果表明在雪荷载和长轴方向风荷载作用下,结构变形与构件内应力均较小。在横轴方向风载作用下,结构产生的横向水平变形较大,结构应力呈反对称分布,应力峰值出现在斜柱中段。由于节点区间隙的影响,持续强风荷载作用下结构产生内力重分布。研究结果可为此类结构的改进与理论分析提供依据。A full-scale experiment of the whole folding frame tent structure under snow and wind loads was conducted.It is revealed that the snow load and wind load in longitudinal direction have small influence on structure deformation and member stress.When the wind load is in transverse direction,the structure represents large deformation and structure stress distribution is anti-symmetrical.The peak value of the stress appears in the middle part of the slantwise columns.Due to mechanical gaps in joint field,continual strong wind will result in evident stress redistribution.The research can provide reference for further structure alteration and theoretical analysis.
