An Experimental Study on the Vertical Vibration Transfer according to Rahmen Building Structures due to Train Loads

라멘조 건축구조물의 수직진동 전달특성에 관한 실험연구

The vibration on building structures due to exciting vibration forces has been studied only for the vibration level on existing buildings. Recently, several researches have been performed on the prediction of vertical vibration on structures by using an analytical method. However, these studies have been focused on mainly the vibration analysis through analytical modeling of structures. This study aims to investigate the dynamic characteristics of vertical vibration transfer from lower stories to upper ones on the Rahmen building structures due to traffic loads. In order to examine the characteristics of vertical vibration transfer, the mode analysis and the impact experiment were conducted several times on one building structures. The results of this study suggest that the characteristics of vertical vibration transfer are different in terms of the type of trains.
