Abstract

The fire performance of concrete-filled steel tubular (CFST) columns has been profusely investigated in recent years, through both numerical and experimental studies. Extensive fire testing on slender CFST columns has been performed in the framework of the European Project FRISCC (Fire Resistance of Innovative Slender Concrete-filled Columns). The results of recent investigations have led to the development of new design rules that allow for the calculation of the buckling load of slender columns in the fire situation, under axial compression as well as combined compression and uniaxial bending. The current design guidelines have been revised and extended by the Project Team SC4.T4 to build up the new method that will replace the current Annex H in EN 1994-1-2. However, the situation of columns subjected to biaxial bending has not been investigated and no fire tests on CFST columns under biaxial bending have been carried out so far. Hence, the extension of the design rules to biaxial bending can only be based on numerical simulations. To ensure the applicability of the model, both tests under biaxial bending at room temperature and tests under uniaxial bending in case of fire can serve for validation. In this paper, a numerical model is presented for simulating the fire behaviour of slender CFST columns subjected to eccentric load in the two sectional axes, which is subsequently used to compare the results with the new design rules for uniaxially loaded columns.
