摘要:In recent years, some scholars suggested that the beam-end of beam-column joint of steel frame can be reinforced by fiber reinforced plastics (FRP) and filled with concrete. In this paper, the reversed cyclic behavior of this new kind of plastic hinge outward joint were studied by finite element analysis. The numerical study shows that, the plastic hinge can be successfully moved outside by reinforced beam-end as reinforced by FRP at the beam end and pouring concrete in the cavity. According to the parameter analysis, it can be found that, as the length of the FRP and the length of the concrete increased, the load carrying capacity and the initial stiffness of the joint increases, but the energy performance of the joint decreases slightly. The thickness of the FRP, paste FRP vertically or horizontally has slightly influence on the cyclic behavior of bolted beam-column joint with FRP reinforced at beam-end.
