Indian Concrete JournalSummary: A finite element (FE)-based numerical model is developed in ABAQUS®, to evaluate the response of steel fiber reinforced concrete (SFRC) columns under combined effects of fire and structural loading. The model utilizes a sequentially coupled thermo-mechanical analysis procedure to trace the fire response of concrete columns. The FE model accounts for temperature dependent properties of the SFRC and reinforcing steel as well as the material and geometrical nonlinearities. Predictions from the numerical model including temperature and axial deflection are compared with the data measured in fire tests to establish the validity of the model in predicting overall fire response of the SFRC columns.
