Abstract
After a school canteen was completed and put into use, cracks appeared in some reinforced concrete beams and slabs of the frame structure. In order to understand the safety of its structure, the structural safety of the canteen was appraised. The appraisal results show that the structural safety of the school canteen does not meet the requirements of the norms. According to the appraisal results, the following suggestions are put forward: (1) strengthening the members whose concrete strength is lower than the minimum requirements of the code; (2) strengthening the structural members whose bearing capacity does not meet the requirements; (3) reinforcing the components with stress cracks; (4) repairing the cracks of the concrete members; (5) repairing the cracks of the filling wall; (6) The school canteen should be suspended and qualified units should be entrusted to reinforce the canteen.
