| Abstract |
Floor vibration has been one of the major problems in residential buildings. Complaints on the floor vibration problem will be growing according to the demands and trends toward the higher environmental performance of buildings. Recently, as one of the solutions of floor impact noise, the application of floating floor structure to residential floor system is considered. However, the applicability of floating floor structure in regard to floor vibration problem is not yet clearly investigated. ??This paper is aimed at investigating the vibrational performance of floating floor structures to footfall loading induced by a human. For that purpose, mock-up tests were carried out in relation with isolating materials incorporated in floating floor structures and the evaluations of vibrational serviceability were performed. The results show that, floating floor structures have??much higher vibration amplitudes in time domain than those of bare floor structure due to the vibrational components of higher frequency range over first natural frequency. |
