Abstract


Concrete exposed to fire can experience spalling when the pore pressure increases due to water evaporation and that results in the surface sloughing off. This works evaluates the consequences that spalling has on the biaxial bending resistance of reinforced concrete columns exposed to fire by means of a sequential model. In this case, it is a sectional model with fibres integration. The model is able to generate the interaction surfaces of the columns subjected to biaxial bending and 4-sided uniformly exposed to the standard fire curve ISO 834.
