  • A deterministic model of impact noise transmission through structural connections based on modal analysis 

    Díaz Cereceda, Cristina; Hetherington, Jack; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2011-01-17)
    Article
    Open Access
    Vibration transmission through structural connections is modelled in a deterministic way by means of modal analysis. This model is used first to study the effect of elastic joints across the floor in the transmission of ...

    The vibration reduction index (Kij) is a key parameter in the prediction of flanking transmissions according to the EN-12354 standard. Formulas for the evaluation of Kij in L, T and X junctions that depend on the mass ratio ...
