INVESTIGATION OF FIRE PERFORMANCE OF CONCRETE FILLED STEEL TUBE COLUMNS

Abstract

In concrete filled steel tube (CFST) columns, while steel confines the concrete and increases the compressive strength, concrete delays the local buckling of the steel. With this study, it is aimed to compile the latest developments related to the factors affecting fire resistance of CFST columns and bring them to the literature. According to infill types, high fire resistance is obtained from steel bar reinforced, steel fiber reinforced and plain CFST columns, respectively, and circular, elliptical, square and rectangular columns according to section type. The fire resistance increases with the increase of the column cross-sectional area. While the increase in the strength of the steel tube leads to a decrease in the fire resistance, it is understood that the thickness of the steel tube does not have a significant effect. In some studies, it is reported that the fire resistance increases with the increase of concrete strength, while in others it decreases. In addition, it is among the findings obtained that the CFST columns produced with concrete containing carbonated aggregate provide higher fire resistance than those with silica. The fire resistance of CFST columns is highly affected by the applied load level and eccentricity and is inversely proportional to both.
