Vibration control in vibration-sensitive advanced technology facilities generally involves design of a stiff floor for the vibration-sensitive area. The authors have found that the range of floor stiffness required for semiconductor facilities and laboratories falls on a continuum between "soft" and "stiff" floors. A significant variation in properties can be observed along this continuum. This paper will review the dynamic properties of floors, addressing the effects of column-slab interaction on their point stiffness and resonance frequency.
