이동하중이 작용하는 곡선보의 MIDAS를 이용한 동해석 기법

초록

Currently, the Ministry of Land, Infrastructure, and Transport’s Smart Construction Technology Development Project is developing unmanned and automated construction and quality control technology for bridges. For piers, a remoteautomated system form for mobile manipulation system technology is being developed. The remote-automated system form has been analyzed for structural safety under static loads, but the dynamic response due to the moving load of the mobile manipulation system has not been analyzed. In the case of curved beams, it is difficult to fully represent the effect of curvature when modeling with segmented straight beam elements. In order to analyze the dynamic response of the remoteautomated system form using MIDAS CIVIL, which uses straight elements, it is necessary to verify the analysis results through a finite element model based on the theoretical analysis results of curved beams. Therefore, in this study, the behavior of curved rails under moving loads is analyzed by comparing the results of theoretical analysis with the results of finite element model analysis using MIDAS CIVIL.
