Vibration measurements for evaluating walking discomfort of floating floors in residential buildings

Abstract

The walking discomfort of floors was evaluated by measuring the vibrational serviceability of a floating floor system on concrete slabs. Several tests were conducted in test rooms to investigate the effects of the measurement position on the floor vibrations. Uncertainties in the vibration acceleration level according to the measurement position were calculated. Based on the results, the walking discomfort was estimated according to the vibration dose value (VDVi), and an in-situ measurement method for floor vibration is proposed, including the number and positions of measurement points. The method was validated through subjective experiments performed in an actual residential building.
