The main process of structural strengthening is 

detection and identification - identification results - reinforcement and retrofitting design - reinforcement and retrofitting construction - engineering acceptance

Detection and identification

Data collection, field investigation, refer to the original design drawings, field data collection, and conduct a comprehensive inspection of the structure of the appearance quality, component damage, cracks, corrosion and structural deformation, the use of environment and load, and the structure of temperature and humidity in the change, the existence of harmful medium, and the actual load whether to exceed the standard.

Identification results

According to the relevant provisions, statistical analysis, processing and evaluation of test data, checking of bearing capacity, comprehensive analysis and judgement of structural safety are made, and evaluation conclusions and suggestions for treatment are drawn.

Reinforcement and retrofitting design

According to the relevant specifications and the results of testing and identification, the reinforcement and reconstruction of the buildings should be designed, and the strengthening construction drawings should be examined.

Reinforcement and retrofitting construction

A qualified construction unit shall carry out the reinforcement and reconstruction according to the reinforcement design drawing, and the supervision unit shall conduct the process supervision, and on-site inspection of the reinforcement construction quality is necessary if necessary.

Engineering acceptance

According to the acceptance code for the reinforcement construction, the parties shall accept the reinforcement and reconstruction project and put them into use.
