为研究考虑屋面构件参与网架结构共同工作抵抗风吸作用的可行性,对各类构件的连接进行讨论,建立考虑檩条、屋面板等屋面构件的精细化有限元分析整体模型。结合某实际工程,通过分析比较檩条与屋面板对于网架结构变形及杆件受力的影响,得出在风吸作用下,考虑屋面构件在整体结构中参与工作是可行的。
In order to study the feasibility of roof members participating in the joint work of grid structure to resist wind suction, the connection of all kinds of components is discussed and the overall model of the refined finite element analysis considering the roofing components such as purlins and roofing panels is established. Combined with a practical project, through the analysis of the effect of purlins and roofing panels on the deformation of the truss structure and the force of the bars, it is concluded that it is feasible to consider the roofing members’ participation in the overall structure under the action of wind suction.
