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.

Design principles for seismic reinforcement of existing building

The strength grade of the material used for reinforcement should not be lower than the actual strength grade of the original material.There should be a reliable connection between the new components and the original components, and the new aseismic walls and columns should have a reliable foundation.
