| Abstract: |
Accidental loads - for example a vehicle impact or blast and shock waves due to detonations - lead to damages in reinforced concrete structures. These damages are characterized by a central zone, which is visually recognizable and also an obvious invisible damage in the surrounding material caused by shock wave propagation through the concrete. To make a statement concerning the structural behaviour of reinforced concrete structures damaged in such a manner and to predict their residual load bearing capacity in a further step, information on the damage is needed. To assess the size of the total damaged zone consisting of visible and obvious invisible parts, non-destructive tests (NDT) have been carried out. Investigations with the acoustical-based Impact-Echo-method and the Radar system based on electro-magnetic waves show good applicability for that problem and help to learn more about damages caused by high dynamic loads. |
