钢管混凝土结构推广应用的关键技术问题之一是节点问题。通过低周反复荷载试验及地震模拟振动台试验 ,对三种型式的钢管混凝土柱框架结构的梁柱节点 (单梁节点、单双梁节点、双梁节点 )的抗震性能进行了理论分析及试验研究 ,研究表明 ,三种节点均具有良好的抗震性能 ,其中尤以单梁节点为最佳。研究成果可供结构设计和工程应用参考 One of the key technical problems in the popularization and application of CFST structure is the node problem. The seismic behavior of three types of column-to-column (single beam, single beam, double beam, double beam) joints of three types of CFST columns are analyzed theoretically and experimentally by low-cycle cyclic loading test and shaking table test Research and studies show that all three kinds of joints have good seismic performance, especially single-beam joints are the best. The research results are available for structural design and engineering application
