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.

Strengthening methods of weak and easy to reverse parts

2) wall seismic capacity of the braced girder can not meet the requirements, can be added for masonry columns, column, reinforced concrete column or the mortar layer, method of reinforcing steel net wall.

How to deal with the different interfaces for reinforcement?

In the reinforcement project, the concrete interface treatment is very important, which is related to the final reinforcement effect. Aiming at the different interface between new and old concrete, new concrete and old brick wall, a series of interface treatment technologies are adopted to consolidate the reinforcement surface and achieve good results.

Working process of structural strengthening

The main process of structural strengthening is detection and identification - identification results - reinforcement and retrofitting design - reinforcement and retrofitting construction - engineering acceptance
