데크플레이트와 경량성형재가 결합된 중공슬래브의 진동성능에 대한 실물실험 평가

The possibility to development of floor vibration problem is larger in case of long span structure under service loads. Therefore, to improvethe vibration performance of the floor, increasing of its thickness is a common method. But, increasing of thickness can lead to increase of slab selfweight and reduce the effectiveness of the building. For this reason, attention for voided slab which reduces the self-weight is increasing. Hence, voideddeck slab combined with deck plate and polystyrene void foam which has buoyancy prevention capacity and much developed construct ability has beedeveloped. By using the developed voided slab, vibration performance of a mock-up building structure has been investigated in the current study.
The results according to analysis showed that they can be implemented in living and bedroom which are considered as 1st grade on the basis of “ResidentialEvaluation Guidelines for Vibration of Buildings” by the Architectural Institute of Japan.
