Abstract

A numerical model to calculate the temperatures, deformations, and fire resistance of loaded circular hollow steel columns filled with steel fiber-reinforced concrete is presented. For the purpose of use in the numerical model, the mechanical and thermal properties of steel fiber-reinforced concrete, expressed as a function of temperature, were determined. Predictions from the numerical model are compared with experimental data. The results indicate that the model is capable of predicting the fire resistance of circular hollow steel columns filled with fiber-reinforced concrete with an accuracy that is adequate for practical purposes. The model can be used to evaluate the fire resistance of circular steel columns filled with fiber-reinforced concrete for any value of the significant parameters - such as load, column section dimensions, column length, and concrete strength - without the necessity of testing.
