Understanding the dynamic response of Ultra High Performance Fibre Reinforced Con- crete (UHPFRC) is one of the most critical issue in the design of protective structures and critical infrastructures which need to withstand explosion or impact actions. These dynamic phenomena cause a different response of the cementitious materials which must be carefully evaluated at the de- sign stage. In the frame of a research aimed to design special shields to protect buildings or critical infrastructures from the effect of IEDs (Improvised Explosive Devices) a comprehensive study on UHPFRCs’ dynamic response has been developed. In this paper are described the different testing set-ups used to analyse the dynamic behaviour of the UHPFRC materials in different failure modes (tension, compression, shear) at high strain-rate.
