Seismic Performance of Reinforced Concrete Beam to Concrete-Filled Steel Tubular Columns Joints

Abstract:

In this paper, eight reinforced concrete (RC) beam to concrete-filled steel tubular (CFST) column joints enclosed by rebars were tested under reversal horizontal displacement with constant axial load in order to study their seismic behavior. The test parameters are axial load level and the section type of CFST column. In this study, the failure model, hysteretic characteristic, ductility and energy dissipation were investigated. The results indicated that the anti-earthquake abilities of all joints satisfied with the demand on the code.
