Seismic performance of a new through rib stiffener beam connection to concrete-filled steel tubular columns: An experimental study

•A through rib stiffener beam connection in CFT circular column is proposed.•Exhibit a large hysteretic enclosed area, good ductility and excellent energy dissipation.•Connection satisfies the seismic provisions and ductility design requirements for moment-resisting frames. This paper proposes a new...
