- W1995206845 abstract "본 연구에서는 교량 통합 부대시설 모듈 구조 개발을 위하여 측면 탈 부착식 교량 방호울타리의 3차원 유한요소해석 및 구조 안정성 평가를 수행하였다. LS-DYNA 프로그램을 사용하여 연결 모듈의 격벽 간격 및 볼트 갯수 변화가 방호울타리 구조의 변위 및 응력에 미치는 영향을 상세 분석하였다. 본 연구에서는 LS-DYNA 프로그램을 사용한 유한요소해석은 콘크리트 바닥판에 삽입된 앵커볼트로 연결된 모듈 위에 설치된 방호울타리의 정적 거동과 구조 안전성을 분석하기 위하여 확장되었다. 수치해석은 6개의 매개변수에 대하여 방호울타리에 발생된 처짐 및 응력분포를 비교 분석하였으며 모두 구조적으로 안전성을 확보하는 것으로 나타났다. This study carried out three-dimensional finite element analysis and structural safety evaluation of attachable roadside barriers. The effects of diaphragm distance and the number of bolts on displacements and maximum stresses for various parameters are studied using the LS-DYNA finite element program for this study. In this study, the existing finite element analysis of barriers using the LS-DYNA program is further extended to study static behaviors and structural safety of the barrier with module structures connected by anchor bolt inserted through concrete bridge decks. The numerical results for six parameters are verified by comparing different models with displacements and stress distribution occurred in the barrier and shows good structural performance." @default.
