도시철도 구조물의 내진설계 및 평가 현황조사

초록

Many structural engineers believed that RC underground structures like subway system might not be seriously damaged during earthquakes, until the Great Hanshin earthquake(a.k.a Kobe earthquake). But there is only one domestic seismic code of rapid transit system that established by Ministry of Construction & Transportation in 2005. Therefore, to investigate of current status on seismic design and evaluation method of rapid transit system is essential to estimate seismic performance of subway structural systems. In this study, comparing domestic codes and seismic evaluation methods with foreign system is performed.
