Abstract

This paper presents an algorithm of the time-dependent analysis of cable stayed bridge with PSC segmental box girder types for design practice. Applied loading conditions at the early stage of construction were self-weight, time-dependent effects and additional construction load. The long term analysis was performed to determine the effects of creep and shrinkage of concrete, respectively. From the result, we can get all information on the behaviors of cable stayed elements not only during entire construction stages but also after construction for long term behaviors. The developed program can be easy to apply for the design of such a cable stayed bridge structure as well as for the evaluation of short and long term behaviors of the structure.

본 연구는 시공초기단계에 자중, 시간의존효과 및 부가적인 시공단계에 따른 건설하중 등을 적용한 PSC 세그먼트 박스거더형 사장교의 실용적 설계를 위한 시간의존해석 알고리즘을 제시한 것이다. 콘크리트의 크리프 및 건조수축 효과를 각각 결정하기 위한 장기거동해석이 고려되었다. 제시된 알고리즘으로부터, 전 시공단계 뿐만 아니라 시공 후 장기거동에 관한 사장교 부재 요소 거동에 관한 모든 정보를 제공해 준다. 제시된 해석 프로그램은 PSC 세그먼트 사장교의 설계에 용이하게 적용될 수 있을 뿐만 아니라 장기 및 단기 거동에 관한 거동 평가에도 간편하게 이용될 수 있는 장점이 있다.
