The paper presents the results of several numerical simulationsperformed with the method on concrete beam sections similar to the ones used in common buildingconstruction. The features of this method are compared with the simplified methods presented in EC2part 1.2, [2]; the 500ºC isotherm method and the Zone method and the results commented.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 228
