Abstract

Nowadays structural engineers, facing critical infrastructure design, must consider severe dynamic load conditions, which reproduce natural actions like strong earthquakes or man-made actions like blast or impact. This research project is centered on the study of a highway reinforced concrete arch bridge, located in southern Italy. The objective is to carry out a complete assessment of the structure under high dynamic loads, validated by in situ test. For this reason a dynamic characterization of materials was performed, through high strain-rate failure tests. A wide range of strain-rate was investigated (from 10-4 s-1 to 10s-1 for the concrete and from 10-4 s-1 to 600 s-1 for the reinforcing steel) and the result will be used to build dynamic models of the bridge that will be analyzed under different extreme loads.
