Seismic Behavior of Connections to Gangue-Filled CFT Columns with Ring Stiffeners
To make full use of the excellent mechanical performance of gangue light-weight concrete, half-size models of joints between steel beams and gangue concrete-filled steel tube columns with ring stiffeners were tested under reversed low cyclic loads. Data collected included extensive strain measurements in key areas of the connection. The data indicates that the behavior of the connection can be adequately predicted by simple mechanical models except in the vicinity of the ring stiffeners. The joints exhibited very robust behavior, with loads increasing until failure was reached due to weld fracture. The cumulative plastic strain resisted by the welds was large, and the gangue lightweight aggregate concrete demonstrated equal or better performance than conventional LW concretes.
