Taking the Civil 2d data and modelling it in ProE represented the model to look at joints mechanically and the general construction.

Then several ProMechanica FEA models were constructed to simulate the structure as beam elements to determine the natural frequencies of the structure and the transmission path into the supporting structure.

Based on Noise Transfer Path Analysis Techniques, a validated FE model of a large frame (supporting a tunnel air extraction fan) was successfully used as the basis for predicting forces into the floor structure with subsequent accurate prediction of fan noise in adjacent properties. Modifications of the supporting structure to better control the noise were successfully assessed in the model before implementation on site. - David Fish JoTech Ltd
