Vibration Characteristics of Low-Vibration RC Floor Structures

Due to the location of vibration sensitive equipment on the floor, it is necessary for its vibration performance to be maintained within stringent limits, resulting in a design of higher mass and stiffness than would be usual for a floor of this type. Modal testing is conducted on the floor to obtain their dynamic characteristics. A considerable level of vibration transmission is observed by comparing the ratio of simulated transfer and point mobility FRFs of the floor.
