First, the theoretical background is presented, the underlying assumptions and approximations are identified and the successive steps of the method are outlined. Then, in order to evaluate the seismic demands produced by SPA, a parametric study of planar and spatial systems is carried out using: (a) the Nonlinear Static Procedure [NSP] as described in EC8 and ATC55 (=FEMA440), (b) the Modal Pushover Analysis [MPA], (c) the SPA and (d) the Nonlinear Response History Analysis [NLRHA]. A 9-story non-symmetric planar frame as well as a set of single story monosymmetric buildings with different inertial characteristics and eccentricity have been analyzed for 20 recorded ground motions using all the above methods. The comparative evaluation of the results shows that, as far as the planar frame is concerned, the magnitude of errors is similar for all approximate procedures, whereas for the single story buildings SPA produces results that are closer to the "exact" ones produced by NLRHA.
