000011371 520__ $$2eng$$aThe nonlinear static procedure (NSP) based on pushover analysis is restricted with a single mode response. Then, the NSP is valid for low-rise buildings where the behavior is dominated by fundamental vibration mode. It is of significance to take into account of higher mode effects in pushover analysis of tall buildings. The present paper attempts to evaluate consecutive modal pushover (CMP) procedure recently proposed to consider higher mode effects. This procedure and modal pushover analysis (MPA) are applied to steel special moment-resisting frames. It is demonstrated that the MPA and CMP procedures are able to overcome the limitation of traditional pushover analysis and to accurately predict the storey drifts of tall buildings. Hinge plastic rotations are noticeably improved by the CMP procedure particularly at top storeys of tall buildings in comparison with those obtained by the MPA procedure.
