Abstract: In order to study the seismic behavior of steel frames in-filled with prefabricated recycled concrete wall, three 1/3 scaled one-bay, one-story specimens were tested with low cyclic load. The behaviors of steel frames with or without the prefabricated wall and with different form of beam-column joints were compared, and the failure mode, transfer mechanism, bearing capacity, ductility and energy dissipation of steel frames were analyzed. The results show that:the bearing capacity and lateral stiffness are improved apparently because of the setting of the prefabricated wall. Compared with the bare steel frame, the ultimate bearing capacity of the specimen is improved by 1.44 times and the lateral stiffness is improved by 3 times. The displacement ductility factor of the specimen is between 2.81~2.86, and the ductility is slightly reduced because of the setting of the prefabricated wall. The bearing capacity degradation coefficient is still greater than 0.90 when the inter-layer displacement angle is 1/50, which indicates that the specimen has a higher safety level. The peak load of the specimen with two kinds of connection forms differs only 4%, which indicates that the beam-column joint connection stiffness has little effect on the bearing capacity of the structure. The failure mode of two specimens is the forming of horizontal crack in connection between the embedded part and the wall, implying shear failure, which indicates that more attention should be paid to the connection of the embedded part in the design.
