Building reinforcement and maintenance 2

The house needs to be appraised

1. Based on the appraisal results

The reinforcement plan must undergo comprehensive analysis, testing, and identification before being designed based on the results. Select reinforcement schemes based on specific circumstances and conditions, with the aim of enhancing the overall integrity of the building and improving the stress conditions of its components, to carry out overall reinforcement, section reinforcement, or component reinforcement of the building.

2. Eliminate adverse factors

For the method of reinforcing components, whether they are newly added or not, the overall adverse factors should be reduced or even eliminated to prevent sudden changes in structural stiffness or strength due to local reinforcement.

3. Ensure reliable reinforcement

The connection between the newly added components and the original components must be firm and reliable; When adding vertical components such as seismic walls and columns, reliable connections should be made.

4. Material strength improvement

The type of material used for reinforcement must be the same as the original structure, and its strength grade must not be lower than the actual strength grade of the original structural material.

5. Dismantle excess hidden danger components

For non structural components such as parapets, door faces, and roof chimneys that do not meet the identification requirements and pose significant safety hazards, their height must be reduced as much as possible and reliable reinforcement construction must be adopted when they must be retained.
