Abstract
In this paper, the effect of cross sectional areas of high strength concrete (HSC) columns at elevated temperatures is investigated. Toward this goal, experimental and analytical studies are performed on short HSC columns subjected to fire. For the experimental studies, the HSC columns are fabricated having different cross sectional areas. The temperature in the chamber is controlled by following the ISO834 time-temperature curve for three hours. During the heating, temperature distributions on different locations inside the HSC columns are measured from the thermocouples. In order to verify the experimental results and to perform parametric studies, finite element (FE) models are generated using the commercial FE software, ABAQUS version 6.10-3. The analytical results of the temperature distributions show good agreement with the experimental results when considering spalled sections of the model.
