For the building structure reinforcement project, it can be divided into the strengthening of the housing structure system and the reinforcement of the components. 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.

Reinforcement method should be adopted when the seismic bearing capacity is not satisfied

1) dismantle or add aseismic wall

2) repair and grouting

3) surface or wall reinforcement

4) reinforcement by external column

5) wrap angle or edge reinforcement

6) support or support
