pushover analysis seems to be a more rational method for estimating the lateral strength and the distribution of inelastic deformations.

These methods were also implemented in recent guidelines [2, 3] based on the new performance-based .

recommend the use of pushover analysis to evaluate the inelastic seismic response [2,5,6], whereas the N2 pushover analysis [7] is adopted in Eurocode 8 [8]. However, the mathematical basis of the procedure is far from accurate; it is assumed that the nonlinear response of a multi degree-of-freedom structure can be related to the response of an equivalent single degree-of-freedom model (SDOF .
