中文摘要：

通过对半刚性铝合金蒙皮结构进行风载和雪载下的极限承载力试验,分析结构的变形和破坏特征。由节点试验得出节点的弯矩-转角关系,并将其应用于有限元分析,研究节点半刚性对结构位移的影响,提出屋面板改变内力在框架内的分布,并大大提高结构承载力。

英文摘要：

An experimental study on ultimate capacity of stressed-skin for aluminum alloy structure with semi-rigid connections under snow and wind load was presented in the paper.The deformation and destruction characteristics of the structure were analyzed.The relationship of M-θ was derived through the joints experimental study.It was used in finite element nonlinear analysis,and the effects of semi-rigid connections on ultimate capacity were also investigated,and it was pointed out that the panels changed the internal force distribution in frames.
