EXPERIMENTAL STUDY OF SLILDING ISOLATED STRUCTURES WITH UPLIFT RESTRAINT

An experimental study of a slender model structure on a sliding isolation system with uplift restraint devices was performed. Shake-table tests were performed on a quarter-scale model of a 6-story steel-braced frame, in which the aspect ratio of height to width was 4.5. The sliding isolation system consisted of sliding bearing augmented with uplift restraint devices to resist uplift forces. The test results demonstrated the effectiveness of the sliding isolation system with uplift restraint devices in reducing the overturning moments and resisting the uplift forces. The analytical prediction of the observed response is also presented. The analytical model includes rocking and variation of coefficient of friction with velocity and bearing pressure.
