Vibration Attenuation At Asymmetric Cross-form Joints of Buildings

The aim of the work is to estimate sound energy transmission through asymmetrical cross‐junctions in buildings. Several kinds of these joints have been investigated. Theoretical calculation model to obtain transmission loss was developed and a system of equations established. The equations were solved and expressions were obtained for predicting transmission loss. Using this procedure for different structural connections, the simplified calculation formulas were received for different cases of asymmetrical cross‐joint. The influence of geometrical parameters and material properties were determined for the sound energy attenuation in the joints of buildings. The obtained results may be applied for evaluation of influence flanking noise transmission through different asymmetric cross‐junctions in buildings.
