They are multi-storey r/c frame buildings, a very spread typology in Italy; in particular, the first has a rectangular plane shape, the second has a L plane shape and the third has a rectangular plane shape with courtyard. The second and the third are irregular in plane according to the rules proposed by the Italian seismic code OPCM n.3431 and by the Eurocode 8 (EC8). Nonlinear static (pushover) and dynamic analyses are performed considering three different seismic zones, with PGA (peak ground acceleration) equal to 0.35 g, 0.25 g and 0.15 g. These are performed using sets of seven earthquakes (each with both the horizontal components), fully satisfying the EC8 provisions. Twelve different earthquake directions are considered, rotating the direction of both the orthogonal components by 30° for each analysis (from 0° to 330°). The analyses have been performed at Significant Damage Limit State, with earthquakes fitting the EC8 elastic spectrum characterised by a return period of 475 years; furthermore, the Near Collapse Limit State is also considered, amplifying the previous earthquakes by a factor equal to 1.5. The results of non linear static analyses are compared to the ones obtained by nonlinear time-history analyses, in terms of demanded / available rotation ratio at the top and at the bottom of each column in the two directions and in terms of maximum frame top displacements.
