PIR-石膏屋面板节点抗剪性能是影响屋面板整体抗剪性能的重要因素。对石膏屋面节点进行了抗剪试验研究，分析了裸钢板和组合板不同板厚下板板连接和板框连接的破坏形式及抗剪性能，并与有限元分析结果进行比较，提出了组合板节点抗剪性能的影响因素，发现组合板节点的抗剪刚度高于单层板节点的抗剪刚度，在自钻螺钉连接时设置垫圈的节点抗剪刚度明显强于不设垫圈的节点抗剪刚度。
PIR-石膏屋麵闆節點抗剪性能是影響屋麵闆整體抗剪性能的重要因素。對石膏屋麵節點進行瞭抗剪試驗研究，分析瞭裸鋼闆和組閤闆不同闆厚下闆闆連接和闆框連接的破壞形式及抗剪性能，併與有限元分析結果進行比較，提齣瞭組閤闆節點抗剪性能的影響因素，髮現組閤闆節點的抗剪剛度高于單層闆節點的抗剪剛度，在自鑽螺釘連接時設置墊圈的節點抗剪剛度明顯彊于不設墊圈的節點抗剪剛度。

PIR- gypsum panel joints shear performance is influenced by roof overall shear properties of important factors. The gypsum roof node for shear experimental study, analysis of the bare steel plate and composite plate with different thickness of plate and frame connection connection damage model and shear properties, and with the results of finite element analysis comparison, proposed a combined plate joints shear performance influence factor, found that the shear stiffness of the composite slab nodes above a node on the single shear stiffness, when the self drilling screw connection setup the node shear stiffness of washer is stronger than the no node shear stiffness of the gasket.
