Geometric Simplification of a Wooden Building Connector in Dynamic Finite Element Model

Résumé

The characteristics of boundary conditions of a wood joist floor are critical in the dynamic behavior at low frequency. Furthermore, the properties of junctions between floor and wall are determinant in the vibrational energy transfer (flanking transmission). For this floor system, the junction between the wall and the joist frame is usually done by wood connectors which present a relatively complex form : folded sheet plate with nails or screws fixing). The aim of this study is to replace the complete model of the connector by an equivalent element in term of transfer functions. The identification of the equivalent parameters is build jointly by numeric analysis and experimental study. In the vibro-acoustic domain, this simplified model reduces the number of vertices, and the resolution time of CAD model building. This simplified structural model can thus be coupled to the acoustics of the adjacent rooms.
