N2 - This paper presents a numerical model to simulate the fire protection performance of a water-based intumescent coating in case of a natural fire scenario. Based on own experimental investigations the insulation efficiency of the coating is expressed by temperature and heating rate dependent material properties within the numerical model, such as expansion factors, thermal conductivities and heat capacities. Within the paper two-dimensional numerical models of a coated I-profile in case of a natural fire scenario are presented taking into account the temperature and heating rate dependent expansion process of the coating explicitly. Moreover, a modelling technique is presented to introduce the material properties of the intumescent coating for both the heating and cooling phase. The results of the numerical models are compared to results of a fire test of an unloaded I-section beam and column. The main objective of the paper is to provide a generic numerical model describing the fire protection performance of the investigated intumescent coating in case of arbitrary natural fire scenarios.
