초록

최근의 건축구조물은 대형화되어 가고, 경량화와 유연화에 따라 진동에 의한 사용성 문제가 제기되고 있다. 일반적으로 RC슬래브의 경우 강성이 우수하여 진동에 대해 비교적 사용성이 우수한 것으로 알려져 있으나, 최근에 시공되고 있는 초고층 아파트의 경우 슬래브가 경량화 되어가고 장스팬을 갖게 되어 이에 대한 사용성의 검토가 요구되고 있는 실정이다. 본 연구에서는 기초적인 연구로 RC슬래브에 대하여 진동에 의한 사용성을 검토하여 보았다. 실험에 사용된 구조물은 충남 천안에 위치한 지하1층 지상5층 규모의 구조물이며 교사로 사용되고 있는 구조물이다. 실험은 모래주머니에 의한 충격하중으로 감쇠율과 구조물의 고유진동수를 측정해 보았으며 가속도센서를 이용하여 1인보행, 2인보행, 1인뛸때의 사용성을 검토해 보았다.

Recent building structures are superior in its ability but they are light weight and long span, and so have problems of vibration. In general, the serviceability of RC slabs was known to be good against vibration because of its hardness. However, recent high-rise apartment slabs are mostly light and long, the serviceability of RC slabs due to vibration could be a problem. In this paper, a basic investigation about vibration problems of RC slabs was performed. Basic information and its influence on vibrations of RC slabs were revealed. Also, its serviceability against vibration was examined. Many tests were conducted for natural frequency of building, for example load of two persons walking and one person leaping etc.
