［摘要］对金属面岩棉夹芯墙面板进行了抗剪性能试验，根据试验结果进行有限元模拟，最后根据试验与有限元结果的对比进行理论分析。结果表明，墙面板连接节点破坏的主要原因是，自攻螺钉由于受到剪力作用，在其与檩条连接处产生力矩，使其发生倾斜，导致自攻螺钉帽斜向接触墙面板，导致局部压力过大，使钢板屈服，最终节点破坏。通过分析，得出了节点抗剪承载力设计公式，为以后节点设计及相关规范制定提供了参考。

Abstract:The shearing capacity experiment was carried out on the color steel sandwich panels filled with rock wool to study the destructive capacity and behavior. According to the result of the tests,the finite element method was used to do the theory analysis. From the result,the main reason which leads to the failure of the joint is that, the self-threading screw is gradient when the force moment is created at the connection, and the cap of screw is contacted with the single nail in a certain angle, which leads to high pressure in the local part and makes the steel plate yielding. By the finite element and theory analysis, the design formula of joint shearing capacity is got, which will be good references for design and code of the joint.

Keywords:the color steel sandwich panels filled with rock wool; joint shearing; finite element method
