Elastic, non linear static and non linear dynamic analyses of a plan irregular multi-storey r/c frame building designed according to Eurocode 2 (EC2) and EC8 provisions are carried out. The elastic analysis is performed by the computer program SAP2000, while the non linear analyses by CANNY99. A set of 7 earthquakes (each considering both the horizontal components), fully satisfying the EC8 provisions, are used as input of non linear dynamic analyses. The problem of extension of N2 method to plan irregular buildings, which makes up for the underestimate of seismic demand on stiff side, is focused: three methods, which take into account the accidental eccentricity provided by modern codes, are proposed. The results, in terms of pushover curves, frame top displacements and interstorey drifts, are compared with ones obtained by nonlinear dynamic time-history analyses. Non linear static analyses are carried out both applying the “modal” and “uniform” force pattern. The “orthogonal effects”, evaluated by SRSS rule, result to be negligible.
