英文摘要	A total of 7 samples were designed to examine the effects of different tectonic modes, axial compression ratio, cross section of the frame column and stressed-skin effect on the seismic performance. Results showed as follows. 1) The joint's failure after skinned is caused by the failure of the self-tapping screws at the wall-floor joint, so preventing the failure of self-tapping screws in the connection is key to success. 2) The bearing capacity and energy dissipation capacity of the recommended joints after covering plate are obviously improved. But the bearing capacity and the energy dissipation capacity are greatly influenced by the height of the section and the ratio of axial pressure. 3) The bearing capacity and energy dissipation capacity of the strengthened joint of angle steel are reduced after skinned, and are greatly effected by the height of cross section. The angle of 2 mm thick specimen is enlarged and reduced in the initial loading. Until all screws are removed from the wall frame and connection completely loses its bearing capacity. Premature failure of self-tapping screws between floor beam and 4 mm thick angle steel specimen causes the bearing capacity to decrease when the thickness increases. 4) The joint's skeleton curve model is obtained, and the basic data is provided for the structural calculation based on simplified mechanical model seismic performance. © 2019, Zhejiang University Press.
