Field Test to Investigate Dynamic Characteristics of Steel Plate Girder Railway Bridges without Ballast
무도상 판형교의 동적거동특성 분석을 위한 실험적 연구
Abstract
Field measurements were conducted to analysis dynamic characteristics of existing steel plate girder railway bridges without ballast. Three bridges which have 9m, 12m, 18m span length in Kyoung-Bu and Ho-Nam Line were selected for test. According to the each bridge, dynamic vertical deflections and vertical and horizontal accelerations were measured. Natural frequencies, vertical deflections and accelerations obtained from field tests were compared with the limit value specified in the UC, Japanese and Korean railway bridge specification.
