内置加劲板加固T型方钢管节点试验研究

摘要

为了研究内置加劲板加固对T型方钢管节点的影响,对1个未加劲节点和1个内置加劲板加固节点进行了拟静力滞回性能试验,结果表明:加固后的节点滞回曲线更加饱满;节点的极限承载力、延性系数比未加固节点明显增加,具有更好的抗震性能.%In order to study the influence of the built-in stiffening plate on the T-type steel pipe joints,the quasi-static hysteresis performance test was carried out on one unenhilled node and one built-in stiffening plate reinforcement node.The experimental results show that the hysteresis curve of the nodes is more complete.The ultimate bearing capacity and ductility coefficient of the joints are obviously higher than those of the unenhanced nodes,and the seismic performance is better.
