Recently, occured earthquakes frequently, there are more security risks of building.The buildings require seismic reinforcement.

In general, the building's seismic reinforcement method has increased cross-section reinforcement method, external reinforcement prestressing method, winding steel wire reinforcement method and bonded (irrigation) steel reinforcement method and bonding carbon fiber composite reinforcement method.

However, no matter what method of seismic reinforcement we choose, and must follow the following requirements, so as to achieve the purpose of seismic reinforcement at the same time maximize the safety of the building.

1, the rationality of the reinforcement program: after building seismic identification, need to determine the type of building reinforcement (the overall reinforcement or local reinforcement);

2, the rationality of the load transfer, as far as possible to maintain the original structure of the rational transmission of ways to eliminate or reduce the original structure of the transmission path defects;

3, in the construction of the time to minimize the damage to the original components
