Structural Design of a Movable Bearing Shoe for Large Bridge Using Three Dimensional Finite Element Method

3차원 유한요소법을 이용한 장대교량용 가동받침 설계

Recently, long large bridges are built for mass transportation. Movable bearing shoes are important components of the bridges because they support movement of translation and rotation of bridge. In design stage of the long large bridges, detailed analyses using the finite element method are performed to guarantee safety and reliability. For that purpose, three-dimensional modeling is carried out by I-DEAS software and finite element analysis by ANSYS software. Results of the analyses are reviewed and important design factors for movable bearing shoes are discussed.
