“…The numerical procedure used in the model is similar to the one that was previously applied to the fire resistance calculations for plain concrete-filled columns (Lie and Irwin 1995). Detailed equations for the calculation of the column temperatures and strength are given by Lie and Irwin (1995).…”

K. R.; Lie, T. T.Evaluation of fire resistance of rectangular steel columns filled with fibre-reinforced concrete V.K.R. Kodur and T.T. Lie Abstract: Experimental and theoretical studies that have been carried out to predict the fire resistance of rectangular hollow steel columns filled with fibre-reinforced concrete are presented in this paper. A numerical model to calculate the temperatures, deformations, and the fire resistance of loaded, rectangular, hollow steel columns filled with steel-fibre-reinforced concrete is described. Predictions from the numerical model are compared with experimental data. The results indicate that the model is capable of predicting the fire resistance of square hollow steel columns filled with fibre-reinforced concrete with an accuracy that is adequate for practical purposes. The model can be used to evaluate the fire resistance of rectangular steel columns filled with steel-fibre-reinforced concrete for any value of the significant parameters, such as load, column section dimensions, column length, concrete strength, and aggregate type in concrete, without the necessity of testing.Key words: fire resistance, numerical model, calculation, square steel columns, hollow structural section, concrete-filled columns, fibre-reinforced concrete.Résumé : Cet article présente des études théoriques et expérimentales effectuées afin de prédire la résistance au feu de colonnes rectangulaires creuses en acier remplies de béton armé de fibres.

“…Test results show that high-strength CFST columns could not satisfy the requirement of fire resistance limit generally, according to Standard CAN/ CSA-S16.1-M89 ''Limit states design of steel structures.'' Many researchers [5][6][7][8][9] conducted a series of studies on CFST members through experiments and theoretical approaches. The studies proposed several methods to compute fire resistance, which has now been adopted in practical design.…”

This study presents the analytical formulation of circular steel tubular column with hollow concrete section. This unified analytical formulation can evaluate the axial compression capacity and buckling load of this innovative composite section at normal and high temperature levels, as well as the normal and recycled concrete in a similar fashion. Therefore, the confinement effect on this composite section is uncertain, which in turn leads to complications in axially loaded compression evaluation, because the inner surface of the hollow concrete section is unrestrained. To this end, this study adopts the effective constraint, which can further assist in transmitting from normal concrete to recycled concrete material to address sustainability issues. In addition, the concept of average temperature is proposed to formulate the failure load of circular hollow recycled concrete-filled steel tubular section and circular hollow concrete-filled steel tubular section columns at high temperature.

“…Lie (1994) developed an analytical procedure to determine the temperature field in composite columns with circular section steel tubes filled with concrete. Lie and Irwin (1995) extended this procedure for composite columns with rectangular steel tube filled with concrete, however, such procedures have proved difficult for practical application. Capilla (2012) researched the slender columns' resistance with circular and elliptical section steel filled with concrete under the action of fire, through numerical simulations, and described a simplified procedure proposed by Leskela (2009), to set equivalent temperatures in concrete and steel in those columns.…”

The composite structures formed by the association of steel profiles with concrete have shown to be an advantageous alternative, improving the behavior of the steel structures concerning their load capacity, stiffness, and durability, under fire conditions. The concrete-filled tubular columns have become an attractive alternative for the civil construction area, offering constructive and esthetic advantages. The Eurocode 4 (EN 1994(EN -1-2, 2002 and ABNT NBR 14323:2013 show simple methods for the design of the composite columns under fire situations. Nevertheless, these present limitations in their application. In addition, regarding the determination of the temperature field in the cross section, the Eurocode 4 (EN 1994-1-2, 2002) describes a specific procedure for columns with section profile covered with concrete, but it is neglectful about concrete-filled tubular columns. The goal of this paper is to present a simplified procedure to determine the temperature registered in concrete-filled steel columns and apply the procedure to columns with square section tubes. The temperature distribution was determined by simulations using the computer package ABAQUS (Dessault Systemes Simulia Corp. 2013). After the studies, it has been considered that the procedure described in this paper is an effective alternative for the determination of the field's temperature and for the application of the design of the concrete-filled columns under fire conditions.
