This research seeks to develop an understanding of the thermal response of steel stay-cables under exposure to a pool fire. Multiple varieties of stay-cable are instrumented with thermocouples and heated by a methanol pool fire. Novel imaging techniques observe the cables surface during heating and cooling and enable the calculation of thermal strains and deformations. Results show a normalization of cross-sectional temperatures outside of the localized heating region for cable diameters up to 140 mm, provide comparisons of heat transfer behaviours for different cable sizes and configurations, present a novel thermal rotational effect, and calculate cable thermal expansion values. Predictive thermal expansion values provided by the Eurocode were shown to underpredict cable thermal expansion in most cases.Author owns copyright, except where explicitly noted.
