The recently developed modal pushover analysis (MPA) for estimating seismic demands on buildings has been shown to be a significant improvement over the pushover analysis procedures currently used in structural engineering practice. By including the contributions of a sufficient number of modes of vibration (generally two to three), the height-wise distribution of responses estimated by MPA is generally similar to the "exact" results from nonlinear response history analysis (RHA). The results presented in this thesis evaluate the accuracy of MPA for a wide range of frame buildings with strong-columns and weak-beams and a ground motion ensemble.
