Abstract

The purpose of this paper is to study of the applicability of the current response spectrum analysis method by grasping the dynamic behavior characteristics of soil-pile and pier-crane in pile mooring facilities. To this end, time history analysis was performed using Abaqus as a design variable for various soil types, pile-ground modeling, and structure specific cycles. The results were compared with the analysis results of the response spectrum. Subsequently, a problem has been found in the current response spectrum analysis and the improvements are needed when considering the dynamic behavior of the ground-pile and pier-crane of the pile mooring facility.

이 논문의 목적은 말뚝식 계류시설의 지반-말뚝 및 잔교-크레인의 동적거동 특성을 파악하여 현행 응답스펙트럼 해석법의 적용성에 대해 연구하는 것이다. 이를 위하여 다양한 지반종류, 말뚝-지반 모델링과 구조물 고유주기 등을 설계변수로 Abaqus를 활용한 시간이력해석을 수행하고, 잔교-크레인의 다양한 연결조건과 구조물 고유주기 등을 변수로 시간이력해석을 수행하여 응답스펙트럼 해석결과와 비교 분석하였다. 연구 결과 말뚝식 계류시설의 지반-말뚝 및 잔교-크레인 동적거동 특성을 고려할 경우 현행 응답스펙트럼 해석법에 문제가 있으며 개선이 필요하다는 것을 확인하였다.
