Flanking sound insulation of wood frame assemblies with high axial and lateral load bearing capacity

As part of a multidisciplinary research project to develop design solutions for mid-rise wooden buildings for the Canadian market, a comprehensive study was conducted on the flanking sound insulation performance of wood frame assemblies that have high axial and lateral load bearing capacity. The axial load bearing capacity depends mainly on framing details and can be increased by strengthening the wall framing by using either more studs at a smaller spacing or by using studs with greater dimension (2 or 3 studs joined together). The lateral load bearing capacity or racking resistance of walls depends on the wall membrane and can be increased by attaching wood board materials (e.g. plywood) in different configurations to the framing. In this paper the effect of shear membranes on the flanking sound insulation of wall-floor systems are presented.NRC publication: Ye
