In this paper, the results of numerical simulation of 2D non-stationary temperature fields in commonly used composite structural members made of steel and concrete in fire conditions were presented. Simulation is based on the model which includes temperature dependence of physical parameters of materials, specific heat and thermal conductivity. Analysis of composite structural members comprises determination of a heat flux field which additionally facilitates understanding of region and geometry ofheat flow, thus enhancing fire protection design. Initial temperature distribution is adopted as uniform, according to Eurocode. Fire conditions were according to ISO 834.The FEM computations for different protection scenario and protective materials for partially encased I section - are conducted in ABAQUS. Obtained results can be used in cost optimization of fire protection measures.
