| 摘要： | This paper investigates the fire performance of concrete-filled steel tubular (CFST) triple-limb laced columns. Six CFST triple-limb laced columns are tested to measure their fire resistance. The influence of column load ratio and steel type on fire resistance are investigated. For comparison, four CFST single-limb columns in fire are tested. The test results indicate that the three CFST chords in CFST triple-limb laced columns can work together very well in fire because of the binding effect provided by the steel lacing tubes. Finiteelement analysis (FEA) models are developed to simulate the CFST triple-limb laced columns in fire. The mechanical behavior, including failure modes, deformation, and load distribution, are discussed. Parametric analysis based on the established FEA model is conducted, and a simplified equation is proposed to predict the fire resistance of CFST triple-limb laced columns. |
