Floor Impact Sound and Vibration Characteristics Affected by the Compressive Strength of Concrete
콘크리트 슬래브 압축강도에 따른 바닥충격진동 및 소음특성

Abstract
In 2005, a regulation on the heavy-weight impact sound was released, which restricted concrete slab thickness of standard floor to 210mm. To reduce heavy-weight impact sound, damping materials and structural reinforcement system have been proposed. In this study, the effect of compressive strength on the heavy-weight impact vibration and sound were investigated. FEM analysis was conducted for the 34PY apartment with different concrete strength (210, 350, 420kg/cm
