ABSTRACT:

Concrete-filled rectangular tubular column composite frame systems with steel beams have been widely used in moment-resisting frames for engineering practice. This paper reviewed a variety of connection details to concrete-filled rectangular tubular (CFRT) columns that have been developed by different researchers. The research on CFRT connections was divided into three phrases. The first phase dates back to the late sixties of twentieth century, when the steel moment-resisting frames were regarded as one of the most ductile systems. The second phase is defined as the period between middle nineties and the beginning of the twenty-first century, during the early stage of which the Northridge earthquake and Kobe earthquake occurred and the conventional knowledge of traditional connections were subverted, leading to the requirement of paying more attention to the investigation of connection behavior under seismic loading. The third phase passes through the following year up to the present. During this phase, various connection alternatives were proposed and studied. Based on the summary of previous studies, the future developments were presented at the end of the paper.
