Steel structure beam column joint with weakened flange beam section capable of being replaced after earthquake and assembling method
The invention discloses a steel structure beam column joint with a weakened flange beam section capable of being replaced after an earthquake and an assembling method. The innovative design of the replaceable component in the replaceable beam-column joint is the key to research the replaceable beam-column joint. The structure comprises a rectangular steel pipe column and an H-shaped steel beam which are connected through a connecting beam section and a splice plate; the connecting beam section comprises an end plate, a weakening flange and a connecting beam section web, and the end plate is fixedly connected with the rectangular steel pipe column through an end plate high-strength bolt; h-shaped steel beam webs and connecting beam section webs are connected through web splice plates and web connecting bolts; and the H-shaped steel beam flange plates and the weakened flanges are fixedly connected through flange splice plates and flange connecting bolts. According to the joint, most earthquake energy is dissipated through plastic deformation of the weakening flange beam section, earthquake damage is concentrated on the replaceable weakening flange beam section, and the weakening flange beam section can be replaced after an earthquake.
本发明公开了一种具有震后可更换削弱翼缘梁段的钢结构梁柱节点及组装方法。可更换梁柱节点中可更换构件的创新设计是研究可更换梁柱节点的关键。本发明包括矩形钢管柱和H型钢梁，二者通过连接梁段和拼接板连接；连接梁段包括端板、削弱翼缘、连接梁段腹板，端板通过端板高强螺栓与矩形钢管柱固定连接；H型钢梁腹板和连接梁段腹板间通过腹板拼接板、腹板连接螺栓连接；H型钢梁翼缘板和削弱翼缘之间通过翼缘拼接板、翼缘连接螺栓固定连接。本发明节点通过削弱翼缘梁段自身塑性变形耗散大部分地震能量，地震损伤集中在可更换削弱翼缘梁段，震后可对削弱翼缘梁段进行更换。
