Abstract
Abstract Constructional practice has shown that structure‐borne sound transmission through joints can signally reduce airborne sound insulation in buildings. Vibration transmission coefficient evaluates this reduction in design calculations. In this article sound transmission through joints in framed buildings is investigated. Rooms in framed buildings are shaped by walls and ceilings connected to columns. Several walls could be connected to each column in a building plan. Such joints are modelled like idealised plate–beam–plate junctions. Examining vibration transmission through these junctions, the influence of a column must be estimated. The column will resist forces and moments applied by the connected walls. The aim of the paper is to evaluate how various properties of walls and columns influence the vibration transmission loss at joints of buildings. The results are compared with the results of similar junctions without columns.
