Analytical Study on Fire Resistance of Unprotected Concrete-filled Tubular Columns Subjected to Double Curvature Bending
Year: 2019
Type: article
Abstract: A concrete-filled tubular (CFT) column is a synthetic structure of a steel tube filled with concrete, which not only possess superior hardness and load-bearing capabilities but is also considered to be highly feasible for use. Therefore, CFT columns are used in steel structures for a wide range of application. CFT columns without fire proofing (unprotected CFT columns), which take advantage of the high heat capacity of concrete, are in high demand for the architectural planning reasons, such as improved aesthetics and reduction in cross sections, and also for the construction reasons, such as their ability to omit the fireproofing process.
