【Abstract】 Based on the experimental investigation of concrete filled steel tubular(CFST) column-reinforced concrete(RC) ring beam joints under static loading and quasi-static cyclic loading,the failure pattern,ductility and energy-dissipation capacity of the joints were analyzed.The test results reveal that the kind of joints can efficiently transfer the internal forces of beams to CFST columns,and has better ductility,energy-dissipation capacity,and can meet the requirements of ductile seismic resistant design.更多还原
