Prediction of building noise and vibration – 3D finite element and 1D wave propagation models

  • Construction work or traffic excite nearby buildings, and the perceptible or audible vibration can be a nuisance for the inhabitants. The transfer of the vibration from the free field to the building has been calculated by the finite element method for many models in consultancy and research work. The analysis for all storeys of certain building points such as walls, columns and floors unveiled some rules, some typical modes, and some wavetype responses. A simplified building-soil model has been created, which includes well these effects of building-soil resonance, wall/column resonance, floor resonances, and the high-frequency reduction. The model consists of one wall for a wall-type apartment building or a column for each specific part (mid, side or corner) of a column-type office building. The building response in the high-frequency (acoustic) region is calculated as mean values over all storeys and over wider frequency bands, by wave-type asymptotes of an infinitely tall building,Construction work or traffic excite nearby buildings, and the perceptible or audible vibration can be a nuisance for the inhabitants.

The secondary noise is predicted by Transfer values between the building vibration (center of floors, walls at a room corner) and the sound pressure.zeige mehrzeige weniger
