Paper Abstract

The dynamic behaviour of modules with different designs and sizes is analyzed with different methods. Outdoor measurements of the deflection show their dynamic behaviour under wind loads and the correlation between wind velocity and deflection. Indoor tests were performed with acoustic excitation of the modules with monitoring the deflection. Numerical calculations, based on FEM-modelling, showed that their resonance frequencies are typically in the range from 1 to 100 Hz. Results of the indoor and outdoor measurements are reported and compared with the numerical results of the FEM-simulation.
