Tenza Bridge Project

Acronym Tenza

Abstract Nowadays, structural design of some critical infrastructures has to allow for events such as blasts, impacts, or strong earthquakes, which force such structures to withstand severe dynamic load conditions, characterized by high intensity and short duration. Therefore, dynamic properties of materials play a fundamental role in the evaluation of the structural behavior of critical infrastructures under such particular events. The activities are part of a wider research project?namely, the Tenza project?are related to this topic. The objective of the Tenza project is to study the effect of high dynamic loads on a reinforced concrete (RC) arch bridge that is part of the abandoned path of the Salerno-Reggio Calabria highway. The bridge was built in the 1960s and retrofitted in the 1990s. Four types of materials can be identified in the Tenza Bridge: 1) the original concrete used in the 1960s when the bridge was built?this accounts for most of the concrete in the structure; 2) the concrete used to strengthen the piers and arches; 3) the original lightly ribbed steel used for the reinforcement of the original concrete; and 4) the new ribbed steel used as new reinforcement.
