Vibration Transmission Through Non-Structural Partitions Between Building Floor Levels

摘要

An assessment of the extent of vibration transmission, attributable to non-structural partitions, was made using experimental tests and numerical simulations, for a recently constructed multi-storey reinforced concrete building. Mechanical excitation was provided to one floor. The extent of vibration on the floor above was found to be as high as 65 % of that recorded on the excited floor. A numerical model was also used to simulate the response to a person walking along a corridor. The extent of transmission was 9 % with partitions and 1.8 % without them. These findings imply that the vibration level on any given floor level will be due to excitation on that particular floor and also the not insignificant level of vibration that may be transmitted through structural and non-structural components due to concurrent activity from floors above and below. This issue of vibration transmission between floor levels is not addressed in any current guidance of floor vibration serviceability assessment and requires further detailed investigation.
