000011351 520__ $$2eng$$aThe employment of Nonlinear Static Procedures (NSP) in the seismic assessment of existing structures (or design verification of new ones) has gained considerable popularity in the recent years, backed by a large number of extensive verification studies that have demonstrated its relatively good accuracy in estimating the seismic response of buildings that are regular in plan (and hence can be analysed by means of planar 2D frame models). The extension of such use to the case of plan-irregular structures, however, has so far been the object of only restricted scrutiny, which effectively ends up by limiting significantly the employment of NSPs to assess actual existing structures, the majority of which do tend to be irregular in plan. In this work, therefore, four commonly employed nonlinear static procedures (CSM, N2, MPA, ACSM) are applied in the assessment of the well-known SPEAR building, an irregular 3D structure tested in full-scale under pseudo-dynamic conditions, and subjected to bi-direction seismic loading. Comparison with the results obtained with nonlinear dynamic analysis of a verified model of the structure then enables the evaluation of the accuracy of the different NSPs.
