摘要
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。
Study on joint is one of the key problems for developing structures of the concrete filled steel tubular(CFST).For this reason,some designers present three joint types:joint of cast in place RC single beam and CFST column,cast in place RC double beams and CFST column,cast in place RC single double beams and CFST column.Anti seismic behaviors and seismic simulation experiments are conducted.According to the analysis and experiments,dynamic behaviors and earthquake response of the three joint types of CFST column frame are to be analyzed.It shows that,three joints,especially the joint of cast in place RC single beam and CFST column,have the favorable earthquake behavior.It will be referred to structure design.
