钢管混凝土柱与钢梁组合节点的抗震试验,火灾中约束钢柱的性能与设计（3）：实用设计方法。
The objective of this research is toinvestigate the seismic behaviour of the composite joint consisting of circular concrete filled steel tubular（CFST） column and steel beam with reinforced concrete（RC） slab.Six speci mens,including four interior and two exterior joints,were tested under constant axially compressive load on the top of the columns and cyclic loads at the ends of the beams.The main experi mental parameters were the type of the joint,the axial loadlevel on the CFST column and the section configuration of the beam.Several indexes that could reflect the seismic behaviour of the composite joint,such as the ductility,the strength degradation,and the energy dissipation capacity were analyzed.It was found that the composite joints exhibited favorable seismic perfor mance.
