In order to reveal the failure mode of extended endplate connections in fire and the effect of compressive stiffener thickness on the fire resistance of connection and the column stability,behaviors of the connection subjected to thermal-mechanically coupling action were investigated.
为研究外伸端板连接节点火灾下的破坏模式及承压加劲肋厚度对节点耐火性能及柱稳定性的影响,研究了热力耦合作用下节点的响应。
Influences of rib stiffeners on hysteretic behavior of end-plate connections;
加劲肋对端板连接滞回性能的影响
L-joints without rib stiffener are semi-rigid connections.
采用简化理论方法对L形圆管节点的强度和刚度进行了分析,横向正应力的存在对节点域钢管具有“捏合”作用,从而降低了节点的刚度和承载能力,无加劲肋的L形管节点属于半刚性连接。
Among them, four end plates are reinforced with rib stiffeners, which are in alignment with beam webs, and constant axial compression force is applied at the end of seven columns during the test.
为了研究钢框架中梁柱端板连接节点的滞回性能,本文进行了8个节点试件的循环加载试验,其中有7个试件的柱端施加了轴向压力,4个端板设置了加劲肋。

The stiffeners that were mounted in compression zone can decrea.
发现:端板厚度对节点的初始转动刚度影响较大,载荷比对转角的影响较大;设置承压加劲肋可明显减小节点域内的塑性应变,改善柱腹板的受力状态,提高柱稳定性,从而保证钢框架整体的稳定性。
