Floating Slab

We conduct extensive finite element modeling, site measurements, and experimental studies on floating slab systems.

Our studies confirm that bending vibration modes of the isolation system can degrade vibration isolation performance. This effect becomes more significant when the bending resonance frequencies of the floating slab coincide with the resonance frequency of the supporting structure, the passage frequency of the support, or the natural frequency of the vertical isolators.

The results suggest that reducing the length of the floating slab or floor can increase the bending resonance frequency, thereby improving vibration isolation performance.
