Investigations on The Prediction Method of floor Impact Sound For Large-Span Slabs Forcused on Aspect Ratio Of Slab Plan

摘要

According to the development of structural design, the varieties of large span slab are increasing. In this paper, the effects and the prediction method are investigated to floor impact sound of the elimination of beams that makes aspect ratio of slab area more than 2 to 6. The high aspect ratio slabs are effective for the heavy-weight floor impact sound because of high mode Density around the first natural frequency was shown.
