The "Euro-Nomogram" is a design aid prepared by the Technical Committee 3 of ECCS. It is aimed at facilitating the calculation of the fire resistance of steel sections exposed to the ISO fire. The nomogram is based on ENV 1991-1-2 and ENV 1991-2-2. The methods given in these codes for the evaluation of the steel temperatures are based on time step calculations with temperature dependent variables. In most cases the use of computer programs is therefore necessary. The "Euro-Nomogram" now makes it possible to calculate fire resistance in an easy way. The explanatory document shows the assumptions made and the way in which the nomogram was developed.
