지중구조물의 내진설계와 개선방향

In this presentation, key features of the design guideline for underground subway structures reported in 2009 are reviewed. The response deformation method (RDM), which is a standard analysis method for the seismic analysis of the structures, is briefly reviewed including theoretical background, characteristics of the analysis results, and some limitations. Finally directions for further improvement of the guideline are presented along with analysis examples.
