000021681 520__ $$2eng$$aA non-adaptive displacement-based pushover (NADP) procedure based on structural dynamics theory is presented to account for the effect of higher modes in estimating the seismic demands of tall buildings. The procedure utilizes some single-run conventional and enhanced pushover analyses. The single-run conventional pushover analysis is carried out using a displacement-based load pattern according to the first mode shape, whereas the single-run enhanced pushover analyses are performed by employing the lateral load distributions obtained by combining the modal story displacements. The modal story displacements are algebraically added; therefore, the signs of modal displacement vectors are retained and the sign reversals in the lateral load distributions are included. To evaluate the NADP procedure, two steel moment-resisting frames with different heights are selected. The results demonstrate that the NADP procedure can accurately estimate the seismic demands at the upper stories of tall buildings in which the effect of higher modes is substantially significant.
