도시철도 시설물의 내진성능평가 방법

초록

A few poblems about the scismic perfomance evaluation method of subway infrastructures, such as cut- and -cover tunnel structures and bridge structures, have been presented recently because characteristics of subway infrastructures are nat properly considered. In this paper, the new and modified evaluation method is proposed. This proposed method involve some of the newly developed or modified engineering technique such shear capacity curve model, ductility- demand-based-design approach for the bridge, failuremechanism due to the plastic hinge for the cut-and-cover runnel, ets.
