Popis: Floors in lightweight framed construction typically consist of wood sheathing and a series of joists spaced at a regular interval. The resulting system is a complex periodic orthotropic plate rib structure with point connections. The ability to accurately estimate the vibration response of the floor sheathing is critical to being able to predict flanking transmission paths involving the floor. This paper begins by presenting vibration data for an isotropic (Plexiglas) periodic plate rib system excited by a single point force. The depth of the ribs was systematically changed to assess the sensitivity of vibration transmission. The measured plate structure is modelled using an analytical solution for an assembly of finite-sized plate strips coupled at a series of parallel junctions. The paper concludes with a discussion of the agreement between measured and predicted results.
