Joints and connections of assembled frame structures are weak in earthquake events, and it is difficult to repair these structures after the earthquake damage. To this end, an assembled buckling-Restrained braced frames structure with replaceable plasticity-deformation controllable steel hinge is presented. Push-over analysis and dynamic time-history analysis are carried out to obtain the seismic behaviour of the new structural such as failure sequence and decreasing ratio for interstory drift angle, and to compare with the traditional assembled frame structure. The results show that the proposed new assembled structure is better than the traditional assembled structure in bearing capacity, lateral resistance, and structural ductility. Also, it can effectively control the nonlinear response of the structure including the displacement of the floor.
