[en] The paper describes an experimental and analytical investigation of the one-shot impact behavior of reinforced concrete beams subjected to varying periods of accelerated corrosion in seawater with induced current. The objective was to simulate long-term field corrosion and determine the reduction in structural integrity. An instrumented electromagnet-triggered dropweight system was used to determine the load and energy traces of beams supported on an isolation block. Three linear physical models, i.e. beam, two and three-degree-of-freedom spring mass, and a nonlinear finite element model, were used and the analytical energy and load values compared with those from the tests.
