Dealing with flanking transmission in wood framed construction

J.D. Quirt, T.R. Nightingale, R.E. Halliwell


A study of flanking transmission in wood frame construction has shown that for airborne excitation the floor/wall junction in multifamily buildings provides serious structural flanking. This can be controlled by systematic changes to the floor and wall assemblies. This paper presents the trends evident from the available data, to provide guidance for practical solutions and indicate some remaining challenges for designers and consultants.
