This solution may be used more frequently in the nearby future. A commonly heard fear on floating buildings is about discomfort from vibration caused through the buoyancy. Large vibrations can be caused when the natural frequency of a floating building pairs with external environmental frequencies. Can vibration be predicted for unrealized floating buildings? This can lead to more optimized floating building designs. This study aims to study deeper on the natural frequency of floating buildings. Vibration frequency theory is verified by measurements. Theoretical formulas are already used by the International Marine Organization (IMO). However, it needs to be tested ‘if’ and ‘how’ they can be applied on floating buildings. For this, measurements are made from floating buildings, as well as measurements on scaled models in laboratory settings. These measurements are compared with the theory. After the theory has been verified, calculations are done on a, yet unrealized, building and its future site to predict the vibration behavior. The result show the theory of the boat movement is applicable to floating building behavior. And as for the vibration serviceability, it’s concluded that the building configuration can be adjusted to fine-tune the natural frequencies of the building, however, the floating environment need to be considered to avoid resonant amplification.
