钢空腹夹层板剪力键节点的极限载荷研究分析

Study on Ultimate Load of Shear Connector Joints in Steel Open-web Sandwich Plate

剪力键节点域是构成钢空腹夹层板的重要关键节点。在ANSYS有限元分析软件下,建立2组考虑材料非线性的数值模型,即设置加劲板宽度和改变方钢管厚度作为研究剪力键节点域极限载荷的影响因素。研究结果表明设置加劲板、增大方钢管厚度均可有效的提高钢空腹夹层板剪力键节点域的极限载荷。

The square steel-tube shear connector joint is an important key node for forming steel open-web sandwich plate.Under ANSYS finite element analysis software,two groups of numerical models considering the non-linearity of materials were established.That is to say,the width of stiffening plate and the thickness of square steel pipe were set as the influencing factors to study the ultimate load of shear connector joints.The results show that setting stiffening plate and increasing the thickness of square pipe can effectively increase the ultimate load of shear connector joints of open-web sandwich plate.
