Measurements on the Characteristics of Dynamic and Vertical Vibration Transfer according to floors of Building Structures using Accelerometer and Dynamic signal analyzer

가속도계와 동적신호분석기를 이용한 건축물 바닥슬래브 동특성 및 수직진동 전달특성 측정

In general, the vertical vibration problems for .strength of members and serviceability of building structures are not considered in structural design process, but the prediction of the vertical vibration is very important and essential to structural design process. This study aims to investigate the characteristics of vertical vibration in terms of the transfer of horizontal directions on the rahmen building structures. In order to examine the characteristics of vertical vibration, the modal test and the impact (heel-drop and hammer) excitation experiments were conducted several times on three building structures. The results from the experiments are analyzed and compared. with the results. The results of this study suggest that the characteristics of vertical vibration transfer in horizontal way are effected from the fundamental frequency of the slabs and excitation forces.
