Rating of A Plate Girder Bridge through Load Test
강거더교의 재하시험을 통한 내하력평가
Abstract
This paper presents the results of the load test performed on a steel plate girder bridge and suggests the procedure of bridge rating through the load test. In general the girder bridge resist the loads as a complex three-dimensional structural system. Therefore the test results are analyzed for the longitudinal and the transverse response characteristics. The bending moments based on the beam analysis are compared with the measured values for longitudinal response characteristics. The lateral load distribution characteristics are assessed based on the load test results for transverse response characteristics. Also the rating of the test bridge is performed by using the suggested rating procedure which considers the actual response characteristics of the bridge. The suggested procedure can be used for understanding of actual response characteristics and evaluating load carrying capacity of the steel plate girder bridge.
