Among the identified modal parameters, natural frequencies and vibration modes are commonly adopted as reference for the model updating process. Dynamic tests are used mainly to identify the modal parameters of the structure. Static tests are normally used to provide only secondary information for the updating process. The FE model updating of concrete structures is usually based on the results of two types of experimental diagnosis tests: (1) static and (2) dynamic tests. On the other hand, adequate FE models are necessary in order to interpret both the results provided from field tests and the structural changes detected by the continuous monitoring of structures. ![]() To guarantee it, the FE models must be checked and updated based on the results of field tests and/or continuous monitoring conducted on the structure. ![]() ![]() In this sense, it is necessary that the structural response predicted by these numerical models adequately reflects the actual behavior of the structure. Sáez, in Eco-Efficient Repair and Rehabilitation of Concrete Infrastructures, 2018 10.7 ConclusionsįE models may be a useful tool to assess the deterioration state of concrete structures and make further decisions about the best strategy for their maintenance and reinforcement.
