The purpose of this paper is to provide information on the behaviour of steel prestressing wires under likely conditions that could be expected during a fire or impact loads. Four loadings were investigated: a) the influence of strain rate - from 10-3 to 600 s-1 - at room temperature, b) the influence of temperature - from 24 to 600 °C - at low strain rate, c) the influence of the joint effect of strain rate and temperature, and d) damage after three plausible fire scenarios.
