All buildings of this study were assumed to locate in Los Angeles and subjected to 20 earthquake ground motions with a seismic hazard level of 2% probability of exceedance in 50 years. These 20-story buildings were designed to conform to the requirements for steel SMFs as specified by IBC 2000 provisions, and the beam-column connections of the buildings were modeled to consider the panel zone deformation. Also, a ductile connection model accompanied by strength degradation was incorporated to the analysis program in an effort to obtain more accurate response results. Three types of the irregularities (mass, stiffness and strength irregularity) specified as vertical irregularities in the IBC 2000 provision were imposed to the original building. Nonlinear static and dynamic analyses were performed, and the confidence levels of which the performance objective will be satisfied were calculated as well. The effects of different irregularity types and levels on the seismic behaviors of the buildings were investigated and discussed in terms of the height-wise distribution of story drifts, maximum story drift demands, global collapse story drift capacities and confidence levels.
