In this paper, the seismic response of eccentrically braced steel frames with partial columns allowed to uplift is evaluated and compared with that of fixed-base frame by numerical analyses, whose prototype test frame of a full-scale six-story eccentrically braced steel building structure was tested by pseudo-dynamic testing technique in Tsukuba in 1982 to 1984. The results show that the base shears in the column-uplift frames are significantly reduced as compared to the fixed-base frames, while the maximum roof drifts of the uplift models are larger than those of the fixed-base models regardless of the input motion intensity because the rotational rigidity of the uplift-column bases in the uplift model decreases.
