도시철도 교량에 대한 내진성능 예비평가체계에 관한 소고

초록

Many problems about the seismic performance evaluation system of subway infrastructures, such as cut-and-cover tunnel structures and bridge structures, have been presented recently. Present evaluation system is not considering entirely special characteristics of subway bridges by simple application of the evaluation system about road bridge. Especially, by unreal evaluation items in preliminary evaluation system for subway bridges, much problems are caused in reliability of evaluation system. This research investigate much problems of existing preliminary evaluation system and propose a modification(revision) plan.
