摘要
梁柱端板连接中为防止柱翼缘冲切破坏,传统做法是将梁端板高度范围内的柱翼缘局部加厚。该文提出一种柱翼缘局部外粘薄钢板加厚的新颖连接方式,并利用有限元软件ABAQUS进行了详细的分析。有限元计算结果表明,此种加强方式在规范/规程规定的传统加厚节点极限承载力标准值范围内,可以达到与传统焊接加厚形式同样的效果,并且可以避免传统形式的施工不便和应力集中等缺陷。最后提出了粘结加强形式节点的粘结层极限荷载的计算公式与节点的构造要求。
To prevent the punching failure of a column flange in beam-to-column end-plate connections,the column flange is required to be thickened within the scope of the end-plate traditionally.This paper presents a new connection that the column flange is reinforced by adhering a plate,and carries out a detailed analysis by the finite element software ABAQUS.The analysis shows that,this connection can achieve the same effect as the usual welding connection within the characteristic value of coded ultimate bearing capacity,and can avoid shortcomings of the usual welding connection such as construction inconvenience and stress concentration.Finally,a formula is given for calculating the ultimate load of adhesive layers,in addition,a construction requirement is suggested.
