Wind Effect on Vibration and Scattering Behavior of Japanese Roofing Tile

A series of wind tunnel tests were conducted on the vibration and scattering behavior of full-size models of tiles widely used as roofing materials on Japanese wooden dwellings. This study has investigated the nature and source of such movement with the aim of providing better insight into the mechanism. The result of these measurements indicates that a basic mechanism can be developed that will lead to flow-induced vibration of the roofing tiles. The values of the oscillation frequencies relate to the values of natural frequencies of the vibration.
