A straightforward calculation method for the fire resistance of reinforced concrete columns

A method has been derived for the fire design of concrete columns in the fire situation. This method has been derived from numerical calculations made with the non linear software SAFIR and has been calibrated to obtain the best fit with the results of 76 full scale experimental tests: 16 performed in Belgium (University of Liege and University of Gent), 39 in Germany (Braunschweig) and 21 in Canada (NRC). The model proposed here has been slightly modified in a later version that is now present in Eurocode 2 (EN 1992-1-2), as tabulated data method A (section 5.3.2). This publication is thus a background document of EN 1992-1-2
