摘　　要：通过对暗扣式屋面板在试验荷载作用下破坏机理的讨论,来分析屋面板在实际风荷载作用下的破坏机理,得出屋面板破坏的主要原因为扣件与屋面板连接处位移过大,因此研究扣件的变形对研究屋面板整体的抗风承载力有着重要的意义.通过大型通用有限元程序ANSYS对扣件进行数值模拟分析,来研究扣件板厚度、突肋高度和螺栓孔位置三者的改变分别对扣件变形的影响,从而得出三者对扣件承载力的影响,为扣件的设计、加工和使用提供参考.Based on a study of the destruct mechanism of buried-shirts roof plate on test-load, the destruct mechanism of buried-shirts roof plate on wind-load was analyzed. The main cause of the destruction is due to large displacement of the roof plate-fastener joints. The research of fastener is significant to the study of wind load-bearing capacity of the roof. Ground on the numerical analysis of the fastener through finite element program ANSYS, the relationship between plate thickness, rib height of fastener, location of bolt hole and its deformation is studied. The conclusion provides a base for the design, processing and aoolication of buried-shirts roof plate.
