High Strain-rate Behaviour of Plain Concrete Subjected to Tensile and Compressive Loading
High strain rate effects is a known problem of concrete, however, due to the difficulty in the realization of tests, not sufficient experimental data are actually available. A large experimental campaign on concrete subjected to dynamic loading has been conceived and implemented at the Joint Research Centre in collaboration with academic and industrial partners. The program has been developed in order to produce data on basic subjects such as: the influence of the increasing aggregate size, of the specimen size and of the relative humidity. In the paper a new experimental methodology to analyse the large plain concrete specimens is described, and the strain-rate effect on strength (tensile and compression), and the fracture behaviour at high strain rate are presented and discussed.
