Effect of Thermal Loading on CFST Element using Abaqus Software

Concrete filled steel tube, or CFSTs, are composite material made up of steel and concrete that have proven to be a useful substitute for traditional steel constructions. They enhance the behavior of steel structures by increasing their stiffness, durability, and load capacity under conditions of thermal loading. An appealing alternative to civil engineering construction is tubular columns filled with concrete. The ABNT NBR 14323:2013 and Eurocode 4 provide straightforward examples of how to construct composite columns that withstand fire. Furthermore, Eurocode 4 specifies a particular process for columns with concrete covered section profiles with regard to determining the temperature field in cross section. The work aims to provide a streamlined process for ascertaining the temperature reported in steel columns filled with concrete, which may be applied to columns including different section tubes.
