Abstract

In this study, a thermal and structural analysis of HSC columns subjected to fire is presented. In thermal analysis, a mathematical and computational model simulating the two-dimensional coupled heat and mass transfer and related processes on high-strength concrete columns exposed to elevated temperatures has been developed. Contours, history, and distribution profiles for temperature, moisture content, and pore pressure are illustrated as model output. In order to validate the proposed thermal model, comparisons between numerical results obtained in the present study and the published experimental results have been performed. For structural analysis, a simple approach to predict the fire resistance of RC columns subjected to fire is adopted and the predictions are validated against experimental test data.
