Abstract

An analytical approach consisting of three sequential analytical steps, namely, fire analysis, heat transfer analysis, and stress analysis was developed for predicting the behavior of CFT columns under fire loading. Analytical models were developed for each of these analysis steps. These included 3D finite element models for nonlinear heat transfer and stress analysis. The analytical approach and models were validated by comparing predictions with experimental results for CFT columns subjected to the standard ASTM fire test. The developed models and analytical approach are recommended for predicting the behavior of CFT columns under fire loading.
