| Abstract |
Although many studies have been conducted for the impact sound insulation and vibration reducing of floor slab, it has been known that the sound insulation performance of floor slab for heavy-weight impact did not show a remarkable improvement. Therefore the study of modified slab systems are required. In this study, new hollow tube system applied to concrete slab is introducedand its performance for the impact sound and vibration is evaluated through experiment. It is known that the amount of materials of concrete and reinforced bar could be reduced in the hollow tube system. Also the proposed hollow tube system could be efficiently used for the electric wire work, air change and air heating. Also, truss-rebar that is applied this hollow tube system plays spacer. As a results of this study, It was known that the dynamic characteristics of hollow slab is very similar to general slab. In case of heavy-weight impact, the performance sound insulation of hollow slab is more excellent than general slab. And there is little difference between this hollow slab and general slab in the impact vibration. |
