Abstract

There are basically two methods for the seismic design of underground structures ; analytical or pseudo-static, and dynamical method. In pseudo-static analysis approach, the ground deformations are imposed as a static load and soil-structure interaction does not include dynamic or wave propagation effects. However the behavior of soil-structure interaction is nonlinear, it needs to consider nonlinear soil-structure interaction effects. In this study simplified seismic analysis method to consider soil-structure interaction by iterative procedure is proposed and the results are compared and analyzed by a finite difference computer program.

지하구조물의 해석 방법은 크게 해석적 또는 유사정적 해석방법과 동적해석 방법의 두 종류로 나눌 수 있다. 유사정적 해석방법은 자유지반변형을 구조물에 정적인 하중으로 적용하여 구조물의 변위를 구하는 방법으로 선형탄성해석에 기초를 두고 있다. 그러나 지진 발생시 지반과 구조물 사이의 상호작용은 비선형 거동을 하여 이를 고려한 해석이 이루어져야 한다. 본 연구에서는 유사정적 해석방법에 반복계산과정에 의하여 지반의 비선형성을 고려할 수 있는 간편해석방법을 소개하고, 이를 수치해석을 통한 동해석을 수행하여 비교 검증하였다.
