Research about Efficiency of Seismic Mitigation for FPS-TMD System

Abstract:

A theoretical analyzing approach about a novel tuned mass damper system, FPS-TMD, was derived according to Lagrange Equation. The solution was presented with Newmark-β method and was programmed with MTALAB software. Computation results show that the maximum storey drift, inter-storey drift, storey velocity and acceleration were significantly decreased with FPS-TMD system. The slide radius, slip friction coefficient and the tuned mass will exert rather large influence upon the efficiency of seismic mitigation and energy dissipation. The system will exhibit the best efficiency with the slide radius being 0.8m, the slip friction factor being 0.4, and the tuned mass M/m=0.5.
