Table 1 collects the EM estimated from static load tests and the outcomes of concrete samples. Figure 10 reports the correlations between the EM and the natural frequencies of the first three modes. The values of the EM derive from static load tests and experimental tests on concrete specimens, indicated in Table 1 by ‘Static Tests’ and ‘Concr. Samp’, respectively. Static load testing is used to assess if the mechanical performance and carrying capacity of the tested structure agrees with design criteria. The adopted test load arrangement followed the recommendations of the Italian technical provisions del Ministero delle Infrastrutture e dei Trasporti (2018).
