The structure vertical vibration isolation requires that the vertical stiffness has weak layer. Vertical vibration isolation technology has been applied in mechanical industry. But in building structures, the application of vertical vibration isolation technology brings the problem of structural overall instability.Keywords: vertical vibration isolation; transfer coefficient; excellent cycle; static displacement; stability
