Abstract

The Model Code 2010, fib Bulletin n. 66, in chapter 9, treats in a complete manner the problem of structural conservation by defining the activities aimed at maintaining a structure to a state which satisfies the defined performance requirements. Deterioration mechanism, deterioration level of materials and structural performance must be determined using appropriate models on the basis of the information obtained from: inspection, testing and monitoring activities, design, information upon previous interventions and environmental conditions. The approach recommended in the Model Code 2010 has been applied to a damaged reinforced concrete building, built in the fifties and now owned by the public administration, devoid of a Condition Control Plan in place. Following the Model Code suggested procedure, a diagnostic campaign, including several non destructive investigations such as visual inspection, magnetic bearing of reinforcement, sonic tests, rebound hammer test, has been carried out on a significant and safe sample of structural elements. Strategies adopted for building conservation and assessment are illustrated and discussed, along with outcomes of the diagnostic campaign
