Abstract

Previous studies have suggested that rocking vibration accompanied with uplift motion might reduce the seismic damage of buildings subjected to severe earthquake motions. 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 frames with column uplift are significantly reduced as compared to the fixed-base frames.
