Abstract

To design retrofit and/or conservation of existing concrete structures, the assessment of concrete strength is generally required. The current methodologies consist of destructive tests (DT) and/or non-destructive tests (NDT). Nevertheless, in several situations (e.g., the seismic vulnerability assessment of long-term service structures), the traditional DT and NDT cannot be used. In these cases, the average strength of concrete (and the relative variance) can be obtained by a statistical approach based on the year of construction. Referring to concrete dams built in the last century, these statistical “strength curves” are used to analyse the seismic criticality of alpine dams, and the corresponding sensitivity to concrete class.
