摘要
对4个不同构造的门式刚架平齐式端板连接节点进行承载力试验及相应的有限元分析,以了解实际工程中该类节点的力学性能,并对节点在正负弯矩作用下的性能进行有限元分析。研究表明,节点域设置加劲肋可显著提高承载力,仅加厚梁端扳对承载力提高作用不明显,平齐式节点非线性特性出现较早。
The bearing capacity tests of 4 flush endplate connections of portal frame with different details were carried out along with their finite elements analyses to comprehend the mechanical property of such connections in practice. The behaviors of these connections under positive and negative moment were analyzed by finite elements method. The results show that setting ribbed stiffener in joint panel zone will remarkable increase the bearing capacity, merely thickening the beam endplate will not improve the bearing capacity, the nonlinear character appears in relatively early stage for flute type column-beam connections.
