Abstract (EN): The concerns regarding the seismic assessment of existing buildings are becoming an important issue for public authorities and the scientific community. Whilst in the US procedures for seismic safety assessment were made available few years after the 1994 Northridge earthquake, in Europe the introduction of a specific Eurocode for seismic assessment only took place few years ago with the publication of Part 3 of Eurocode 8 (EC8-3). The experience with the application of the European code is therefore very limited. Few studies related to the application of the EC8-3 procedures to RC structures have already been conducted, but none have been performed for the case of steel structures. In this paper a comparative study of the European and American seismic safety assessment procedures as defined in EC8-3 and in the ASCE41-06 is carried out. To this end, the two standards are employed in the seismic assessment of four different steel buildings, designed according to different criteria. Special attention is devoted to the use of linear elastic analysis methods, both in terms of their applicability criteria and corresponding safety checks. The main results in the study are discussed and the difficulties in the application of the European code are identified.
