본 연구에서 제안하는 중량충격음 저감방안은 대상 구조물의 강성을 증가시킴으로써 슬래브 하부로 전달되는 충격진동을 저감하는 방법이다. 우선 구조물 자체의 성능에 대하여 콘크리트 재료의 강성, 즉 압축강도를 증가하는 방법과 슬래브 구조의 중량을 증가시킴으로써 구조체의 강성을 보강하는 방법을 고려하였다. 또한 기존건물에 대한 보수보강 개념으로 고강성의 구조부재를 구조체에 적용함으로써 구조강성을 증가시키는 방법에 대해서도 고려해보았다. |

The effects of the structural stiffness of concrete slabs on the floor impact noise, were investigated through the field measurements and computational analysis. In this study, the various methods to reinforce slab structures were applied: increment of compressive strength and slab thickness of slab structures and attachment of a F.R.P. beam under the ceiling. Floor impact sound and vibration were evaluated by the field measurement and the FEM using the heavy-weight impact source. As a result, it was found that the floor impact sound pressure level (Li,Fmax,AW) was decreased in spite of increase of the compressive strength due to increment of SPL at 63 Hz. In case of a single slab in the floor impact sound test building, it was observed comparatively that impact SPL was decreased 2 dB every 30 mm increment of concrete slab. The range of concrete thickness was from 150 mm to 240 mm. However in case of a composite slab, it was observed little decrease of impact SPL. In case of attachment of FRP beam under the slab, the floor impact vibration acceleration level and impact SPL were reduced up to 3 dB and the resonance frequency of the slab was increased. The measurement result of the application of FRP beam in the test building was similar to FRP plate on whole slab in the vibration analysis. |
