Abstract
The thesis presents seismic response assessment of older non-residential single-storey steel buildings designed in the decade 1980s-1990s in Italy. To this end, multiple building archetypes were considered. The selected case studies are characterized by (i) a main truss system in the transverse building direction and (ii) a concentric braced system in the longitudinal building direction. Various structural schemes and two alternative brace cross section types were considered. 3D non-linear finite element models were built and analysed using OpenSees. The analysis was carried out considering or excluding the contribution of envelope panels to the seismic response. Both Non-linear static and dynamic analyses were used to assess structural response up to reaching global collapse of the building. Eventually, collapse fragility curves were built starting from results of non-linear dynamic analyses. Comparisons among the models were also carried out to emphasize the building lateral strenght, elastic lateral stiffness and global ductility.
