The effects of structural irregularities in stiffness, strength, mass and combination of these factors are considered. In other words reliability of the modal pushover analysis (MPA) has been verified by defining a referenced regular structure for comparison between MPA and nonlinear dynamic analysis. Using two analysis method for vertically irregular and regular frames leads to the following results: (1) the mass irregularity conditions were found to have a negligible impact on the seismic performance of building, (2) The accuracy of modal pushover analysis to estimate the seismic performance increases when irregularities conducted at lower half stories, (3) Additionally the accuracy does not deteriorate when irregularities provides in the middle or upper story, and (4) Time saving and accuracy besides conceptual simplicity of MPA in brief leads to reliable estimation of seismic performance.
