지반 구조물의 내진 설계를 위한 지반응답 해석기법의 비교연구

Abstract

Ground response analysis is one of the most important and most commonly encountered problems in geotechnical earthquake engineering. It is a prerequisite step for liquefaction assessment of saturated soil or the pseudo-static and dynamic analysis of geotechnical structures. A number of techniques have been developed for ground response analysis. In this study, ground response analyses were performed using the computer programs that are currently being used domestically. From these analyses, the analysis techniques applied to the programs, and the characteristics of the techniques were compared and analyzed. Ground response analysis results were arranged as follows: 1) 1-dimensional analysis vs. 2-dimensional analysis, 2) equivalent linear analysis vs. nonlinear analysis, and 3) verification of the effectiveness of absorbing boundary condition.
