A Study for Vibration Characteristics of RC Slab with Hybrid Beams in Large Span Educational Facilities

대공간 교육시설에 사용되는 합성보 및 콘크리트 슬래브의 진동평가에 대한 연구

In this study, vibration characteristics of reinforced concrete slab in large span educational facilities were evaluated. A 21.75m X 14.4m full scale reinforced concrete slab specimen was constructed with pre-flex hybrid beams. Vibrations were generated by three different methods such as free falling method of a 6kg sand bag, a 70kg person walking method and impact method by impulse hammer. Vibrations were generated more than 3 times at single location. Vibration characteristic data were collected by SA390 signal analyzer machine at 5 different locations.
