Abstract

Prediction of Flanking Transmission for lightweight constructions is a sensitive procedure.
Lightweight structures are anisotropic and are composed of multiple possibilities of build-ups
and structural junctions. The article presents an example of structure composed of Cross
Laminated Timber. The modelling strategy to predict such structures is detailed. The framework
of the methodology is Statistical Energy Analysis (SEA). SEA involves cutting the structure into
subsystems and decomposing the spectrum into third-octaves or octaves. In this way, the
exchange of energy flow in the substructures can be analysed. The parameters that govern
vibrational transmission between subsystems are damping and coupling loss factors and can be
identified experimentally by reversing the problem. The approach is, first, based on substructuring
strategy of structure; second, on experimentally measured coupling and damping
loss factors; third, on extracting vibration level difference to estimate one by one all flanking
passes.
