Abstract (EN): This paper focuses on the evaluation of a set of Nonlinear Static Procedures (NSPs), applied to groups of plan-regular and irregular steel structures with three stories. The NSPs selected are the conventional and the Extended N2, the Capacity Spectrum Method and the Adaptive Capacity Spectrum Method. In terms of translational response, all NSPs lead to adequate estimations of results. Concerning the torsional response, the results of the Extended N2 are the most appropriate to the studied irregular steel structures, except for torsionally stiff concentrically braced frame structures. An improvement version of the Extended N2 method is proposed for these structures.
