SHAKING TABLE TEST OF SEISMIC CONTROL SYSTEM USING FORCE RESTRICTED TUNED VISCOUS MASS DAMPER

Abstract

Force restriction of the tuned viscous mass damper is considered using a friction slider. From a series of shaking table tests, it is shown that the restriction mechanism can effectively reduce the damper maximum force, and the maximum displacement of a primary system incorporated with the force restricted damper is almost the same as that with a restriction-free damper. The simulation analysis results show good agreement to the experimental results, and the relationship between the ratio of the force restriction and the maximum displacement is examined by the analyses.
