Abstract

Long-span open plan floors are structures that may suffer excessive vibrations when subjected to dynamic human-induced loading. When a multi-input multi output vibration control strategies is planned to be installed in order to reduce vibration levels, a modal model should be derived for designing purposes. Thus, the research team has planned the dynamic testing of an in-service open planned dinning hall sited in Pozuelo (Madrid, Spain), as a previous step of the control design. First, a finite element model (FEM) of the structure has been made from architectural drawings and visual inspection of the structural elements. Second, an operational modal analysis has been undertaken using 18 high-sensitivity accelerometers and through several setups covering the whole floor. Also, frequency-response-function analyses have done using an electrodynamic shakers placed consecutively at two different selected locations. The input excitation was a chirp signal exciting the structure in a broadband frequency spectrum. Finally, the FEM model has been calibrated taking into account all the test undergone and accurate broad-band-frequency modal model has been derived for the design the active control strategy.
