At present, the performance-based earthquake-proof design becomes the mainstream of earthquake-proof design, and how to enable the whole building, even the whole city and even the whole society to have the recovery function after an earthquake occurs has brought close attention and wide discussion to the earthquake engineering world in recent years. How to design a structure which can not be damaged or only be damaged quickly in the earthquake becomes one of the important research directions for the sustainable development of engineering earthquake resistance. By weakening some parts of the structure system and realizing concentrated energy dissipation at the parts, the damage of the structure under the action of earthquake can be effectively controlled, and the damaged parts can be replaced to ensure that the building can quickly recover the function after the earthquake.
After the earthquake, the end part of the concrete frame column foot can generate plastic hinge, and the stability of the whole structure is influenced. The column base is difficult to repair after being damaged, and the restorability after the earthquake is poor. If the damage is concentrated on the energy consumption mechanism, the function of the structure can be quickly recovered only by replacing the energy consumption mechanism after the earthquake.
