Earthquakes have always been one of the injuries to humans in natural disasters. After the earthquake, building structures were severely damaged, cracks, and even collapsed. Therefore, the purpose of seismic strengthening of existing buildings is to make existing buildings meet the basic requirements of seismic strengthening. That is to say, in the event of an earthquake, the building structure will not collapse and hurt people.

After the earthquake, various disaster relief work was carried out in an orderly manner, and the repair and reinforcement of buildings was a top priority. So, how can buildings be reinforced?

After the earthquake, the appraisal department will conduct an earthquake appraisal on the building, and then carry out seismic reinforcement design of the building based on the results. As we all know, the traditional seismic reinforcement methods include sticky steel reinforcement, enlarged section reinforcement method, and winding wire reinforcement method. Today, I will introduce a kind of reinforcement material that is both affordable and easy to use --- Horse Construction carbon fiber cloth.

Carbon fiber cloth reinforcement method is a new reinforcement method in recent years. It has its advantages in strengthening structural cracks and insufficient bearing capacity. As the country strengthens the seismic reinforcement of buildings, carbon fiber cloth has exerted its excellent performance, but it has made great achievements in seismic reinforcement. We know that in a building, the real load is the pillars. Therefore, during the reinforcement, in order to improve the ductility of the column, we will use the carbon fiber cloth ring bundle method to strengthen the column. A circular constraint is imposed on the concrete column to improve the axial bearing capacity of the concrete and the ductility of the concrete column to achieve the purpose of seismic reinforcement.

When using carbon fiber cloth for seismic reinforcement of buildings, the following principles must be followed:

1. Because the building itself is severely damaged, it must be ensured that the structure of the building is not damaged twice during the construction process. So at present, carbon fiber cloth reinforcement is a reinforcement method for small building losses, and it is recommended to promote it in disaster areas;

2. After the seismic evaluation of the building, determine the reinforcement method suitable for the building, and do not directly construct it based on experience. After all, this is a matter of human life;

3. The rationality of load transmission, try to maintain a reasonable force transmission path of the original structure, eliminate or reduce the defects of the original structure force transmission path.
