Vibration Characteristics of Low-Vibration RC Floor Structures

저진동 RC 플로어 구조의 진동특성에 관한 연구

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.
