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。

Abstract: 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- 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.
