梁与预制长柱明牛腿刚性连接节点在冶金、电力、化工、煤炭等工业部门的装配式钢筋混凝土多层厂房中得到了广泛应用。这种型式的节点具有承载能力大、受力可靠,节点刚性好以及安装方便等优点,但过去在设计中,一般都未考虑抗震。通过国内外多次大地震的震害调查说明:节点是框架结构最易受损的部位,节点的破坏往往导致整个 Beams and prefabricated long-column bulge rigid joints have been widely used in prefabricated reinforced concrete multi-storey factory buildings in metallurgical, power, chemical, and coal industries. This type of node has the advantages of large bearing capacity, reliable stress, good rigidity of the node, and easy installation, but in the past, seismic design was generally not considered. The seismic damage surveys of several large earthquakes at home and abroad show that the nodes are the most vulnerable parts of the frame structure, and the destruction of the nodes often leads to the entire
