[en] A parametric study of 13,608 ductile Moment-Resisting Steel Frames (MRSF) designed according to Eurocode 3 and Eurocode 8 is performed. A flowchart for the evaluation of the seismic-resistant capacity of the designed frames is developed based on the N2 method. The design structural overstrength, the ductility supply, the plastic redistribution parameter, the supply reduction factor and the performance ratio of the frames under study are analysed. The 13,608 designed frames under study have performance ratios higher than one mostly due to the high values of design structural overstrength, showing that the seismic supply produced by Eurocode 3 and Eurocode 8 restrains are always higher than the seismic demand.
