Abstract

In this paper, we attempted to analyze vibration properties depending on construction deviations of concrete slab, and 12 specimens of 8 4 types were selected. The floor impact sound blocking performance measurement method was performed according to the standard weight impact source method among the KS F 2810 field floor impact sound blocking performance measurement methods. As a result, as the compressive strength of the slab increased, the amount of vibration decreased at a frequency of 31.5Hz, while the amount of vibration increased at 40 to 100Hz. As the slab thickness increased, the vibration level increased at a frequency of 31.5Hz and decreased significantly at frequencies between 40 and 100Hz. The level of vibration decreased with the thickness of the weakly bonded center point.

본 논문에서는 바닥슬래브의 시공편차에 따른 진동 특성을 분석하고자 하였으며, 이를 위해 84 type 총 12개의 시험체 진동레벨에 대해 평가하였다. 그 결과, 슬래브의 압축강도가 증가함에 따라 31.5Hz 주파수의 진동레벨은 감소하지만, 40~100Hz 주파수는 진동레벨이 증가하였으며, 이와 반대로 슬래브 두께는 증가함에 따라 31.5Hz 주파수는 진동레벨이 증가하였고, 40~100Hz 주파수는 진동레벨이 감소하였다. 본 연구 결과는 평판이 넓고 구속력이 작은 중앙지점 두께에 의존하여 진동레벨이 감소한 것으로 판단된다.
