Unwanted vibration levels in building structures either from machinery or human activities can affect the comfort of occupants and therefore they should be reduced or controlled to ensure that the adequate level of serviceability. In this paper vibration levels assessment of a beam and block floor are evaluated. This type of structural system is prone to vibrate due to the inherent flexibility and reduced mass when compared with reinforced concrete slabs. Numerical and experimental analyses were carried out to assess the vibration of an actual prefabricated beam and block floor. Although there was found some differences between the numerical and the experimental model, it was verified that the vibration level is within the allowable range to ensure the vibration serviceability regarding the comfort of the building occupants.
