Abstract

Reliability analysis of pile type quaywalls were done by using response surface method. Pier structures have implicit form of limit state function since they are flexible in motion, which is different from gravity type quaywalls. To solve a reliability analysis problem with implicit limit state function, response surface method was applied. Reliability indices of structure under seismic load were found for pier structures Then, they were compared with those found by simulation method. In numerical analysis, both the inclined type and vertical type were analyzed.

응답면 기법을 사용하여 잔교식 안벽의 신뢰성 해석을 수행하였다. 잔교식 안벽은 중력식 안벽과 달리 상부가 강관파일에 의해 지지되는 유연구조물로 한계상태함수가 음함수로 존재한다. 따라서, 한계상태함수를 양함수로 근사하기 위해 응답면 기법을 사용하였다. 응답면 기법을 이용한 LevelII신뢰성해석 방법을 통해 지진하중에 의한 잔교식 안벽의 신뢰도지수를 계산하고, 중요도 추출법을 통해 검증하였다. 수치해석으로는 직항식, 사항식을 각각 해석하였다.
