The column is the main component bearing the vertical load, and the damage of the column is the direct reason causing the structure to collapse, so the layer yield damage caused by the hinge-out of the column end is not beneficial to the improvement of the anti-seismic performance of the structure. In addition, the number of plastic hinges of the layer yield mechanism is small, and the energy consumption capability is small; under the action of axial compression, the deformation capability and the energy consumption capability of the column hinge are small, and the anti-seismic performance of the structure is further reduced by the action.
