With the acceleration of urbanization and the advancement of modernization, although many old buildings are far from reaching their service life, their performance can no longer meet current requirements. In recent years, a large number of old building reinforcement and renovation projects have appeared. Let's introduce the design principles of reinforcement and retrofitting of old buildings:


1. Based on the identification results


The plan should be designed after the comprehensive analysis and evaluation results, and the reinforcement plan should be selected according to the specific conditions and conditions to enhance the integrity of the building, improve the stress status of the components, and carry out overall reinforcement, section reinforcement or component reinforcement.



2. Eliminate unfavorable factors


Regarding the arrangement of reinforcement members, whether they are new members or not, the overall disadvantages should be reduced or eliminated to prevent sudden changes in structural rigidity or strength caused by local reinforcement.



3. Ensure the reliability of reinforcement


The connection between the new component and the original component should be firm and reliable. For example, additional vertical components such as seismic walls and columns should have a reliable foundation.



4. Strength of the structural strengthening material


If the structural strengthening material type of the reinforcing member is consistent with the original structure, the strength grade shall not be lower than the actual strength grade of the original structural material.



5. Eliminate redundant hidden components


The height of non-structural components that do not meet the appraisal requirements must be retained, such as parapets, door faces, roof chimneys, etc., and reliable reinforcement measures must be taken.
