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。
The deformation and failure characteristics of the structure are analyzed through the ultimate bearing capacity test of semi-rigid aluminum alloy skin under wind and snow load. The bending moment-rotation angle of the joint is obtained from the joint test. The finite element analysis is used to study the influence of the semi-rigidity of the joint on the structural displacement. The distribution of the internal force in the frame is proposed and the bearing capacity of the structure is greatly improved.
