Evaluation of vertically irregular frames using the existing methods like the Modal Pushover Analysis, Extended N2 method etc. are known to have certain drawbacks due to the elastic higher modes they consider. The method proposed here is based on the inelastic drift patterns of irregular frames. It is developed from the shear distribution model proposed by Chao et al (2007) for eccentrically braced steel frames. It eliminates the computational complexity involved in the adaptive load pattern procedures which are considered suitable for irregular frames. Comparison of the proposed procedure with the extended N2 method is done on three dimensional 10 storey RC frame with vertical geometric irregularity. Results show that better predictions of structure stiffness and interstorey drift demands are obtained by the proposed method.
