Evaluation of Serviceability due to Vibration of Slab

건축구조물의 슬래브 진동에 의한 사용성 평가 연구

Recent building structures are superior in its ability but they are light and fiexible, 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 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 on existing building located in Chung-Nam area. As a results, damping ratio, natural frequency, acceleration amplitude and displacement amplitude which were used to examine serviceability of the RC slabs were obtained. These results on the test building proved that its serviceability conditions were satified to meet the code against vibration.
