Reinforcement of bridge with epoxy bonded steel plate
The bonding steel plate reinforcement method is to apply epoxy resin series adhesive on the steel plate, and then paste it into the weak part of the reinforced concrete structure's tensile area, the steel plate and the structure form the whole, and the additional reinforcing bar is added.

Which buildings need seismic strengthening?
In order to protect the life and property, the building have to do seismic strengthening. However, some buildings have not been aseismatic in the design and construction, which requires the seismic identification and reinforcemen . In particular, the old buildings, such as the general hotel, need to be identified as a whole in the new era and to be reinforced in accordance with the design.

The main reasons for structural strengthening
The main reasons for structural strengthening:materials reson(unqualified cement quality),design reason(lack of security design),change usage(seismic reinforcement of existing buildings),construction reason(construction method is wrong),environment reason（concrete corrosion，corrosion of steel bar）

Why does structural reinforcement need to removed the load?
if the load is removed before the reinforcement of carbon fiber cloth, the situation is completely different. Due to reducing the influence of two times of load and decreasing the lag strain of CFRP, the old and new two parts can enter their respective limit state at the same time, and the overall bearing capacity of the structure can be significantly improved.

The method of reinforcement of RC structure
The following reinforcement methods should be adopted when the structural system and the seismic bearing capacity of reinforced concrete buildings are not satisfied

Reinforcement method should be adopted when the seismic bearing
System reinforcement is aimed at the overall seismic performance of the building structure which is less than the current seismic appraisal standard, and the reinforcement is reinforced by local members for the lack of bearing capacity of the local members.
