Nonlinear Finite Element Analysis of the Temperature Field of Special-Shaped Concrete-Filled Steel Tubular Column under Standard Fire Condition

Abstract:

The special-shaped concrete-filled steel tubular column (SCFST column) is recognized to have high bearing capacity and good fire resistance. This paper introduced a nonlinear FEA approach to analysis the temperature field of SCFST under standard ISO-834 fire condition. Finite element model was built with nonlinear material properties elements in ANSYS; thermal boundary conditions were applied to the model with convection and radiation combined to simulate the fire condition, and several conclusion were obtained from the nonlinear FEA results.
