Development of Macro Element for the Analysis of Prestressed Concrete Box Girder Bridges

프리스트레이트 콘크리트 박스거더교량 해석을 위한 매크로요소의 개발 및 유한요소 정식화(1)

A Formulation based on macroelement concept is developed to analysis the prestressed concrete box girder bridges. The proposed method enables to model the arbitrary shapes and boundary conditions of prestressed concrete box girder bridges. The validity of the algoriyhm is demonstrated through comparisons with other results.
