Abstract

The authors have proposed the tuned viscous mass damper system based on the fixed points theory, and have proved the validity of the theory and the analysis method through the vibration tests of the small scale test specimen. The testing program revealed that an increase in equivalent inertial mass of viscous mass damper and increase in input resulted in an excessive stresses in the supporting member, damper body and the primary structure connected to the damper. In this paper, authors built the rotation slipping mechanism into the main body of the full-scale tuned viscous mass damper with the spring member of 18,200kN m and the equivalent inertial mass of 1,35Oton, and tested the tuned viscous mass damper with the force restriction mechanism. Analysis parameters of the tuned viscous mass damper with the force restriction mechanism were evaluated accurately and the test results corresponded well with the analytical results. From the analysis results for a 1-story structure, it is shown that this restriction mechanism can effectively reduce the damper maximum force and the maximum response displacement is almost the same as the result obtained by a restriction-free damper.
