Advantages such as high ductility, reduction of dead load and higher energy dissipation of the structures made with steel beams and concrete columns compared to conventional reinforced concrete structures have resulted in the widespread use of these structures. On the other hand, the provisions of different codes of RCS connections lead to complex details and implementation. In this paper, the behavior of steel beam to circular concrete column connections was experimentally studied. Five real scale external RCS connections were made and tested. Variable parameters of the specimens were included the tie spacing around and inside the connections, confinement around the connection region with CFRP sheets and concrete type. The aim of the study was to propose a connection with simple details and desirable behavior. The results indicated that the proposed connection can appropriately transfer the moment from the steel beam to the concrete column in addition to having simple implementation. Also, the confinement of the connection region with CFRP sheets increased the ductility and energy dissipation of the RCS.
