Sound transmission between columns and floors in framed buildings

In framed buildings joints between columns and floor structures commonly occur. Beams at the top of columns, which support the floors, increases the complexity of the joint and can greatly influence the transmission characteristics. Impedances for composite beam/plate structures are used together with wave theories to obtain predictions for vibration transmission at such joints. Predictions of sound transmission at such joints are computed within a statistical energy analysis framework and good agreement is found between measured and predicted results. © 1993.
