000012844 520__ $$2eng$$aThe effect of high strain rates on the tensile properties and the fracture behaviour of structural steels is of critical importance to blast performance in presence of fire. Data on the effect of high strain rate on tensile properties is scarce due to testing difficulties. The main objective of this investigation is to include high strain rate effects for the evaluation of mechanical response of steel structures under combined effect of fire and blast. High temperature and high strain rate data are presented for the commonly used S355 structural steel. Specimens consisting of round samples with 3 mm in diameter and 5 mm of gauge length were used. Tests were performed by means of a Split Hopkinson Tensile Bar (SHTB) to understand the behaviour at high strain rates (300 s−1, 500 s−1 and 850 s−1) and at different high temperatures (200°C, 400°C, 550°C, 700°C, 900°C). A marked difference between quasi-static and high strain rate reduction factors was highlighted, while the tensile properties at high temperature do not seem to be significantly influenced by the different dynamic testing conditions.
