In this paper results are presented from a by STW funded research project “spalling of concrete due to fire exposure” between Eindhoven University of Technology and Delft University of Technology and aimed at developing an integral spalling model. In this paper two coupled Finite Element based models are presented in which the first model describes the physical behaviour of concrete and is used to determine the temperature and pore pressure development and the second model describes the fracture mechanics behaviour of concrete and is used to determine the crack development.
