by The provisions of the “Reliability Appraisal Standard for Civil Buildings” (GB50292-2015) regarding the safety appraisal of concrete structural components should be evaluated based on four inspection items: bearing capacity, structure, displacement or deformation that is not suitable for bearing, cracks or other damages, etc.
The grade of each inspected component should be evaluated separately, and the lowest grade should be taken as the safety grade of the component.
