Abstract (EN): A new generation of performance based seismic design procedures is emerging during the two last decades. These methodologies aim to provide the designers with better control of deformation and, consequently, of the structural damage. The Direct Displacement-Based Design (DDBD) is one of the most promising displacement-based design methods. In this paper a comparison between different seismic design procedures for steel moment-resisting frames is presented. A set of steel moment-resisting structures are designed according to Eurocode 8 (EC8) and to the direct displacement-based design. The performance assessment of the structural systems is performed through nonlinear static and time-history analyses. The results obtained allow concluding that the structures designed according to DDBD do not necessarily exhibit better structural performance in comparison with those designed according to EC8.
