Prestressed concrete PSC girders are efficient in terms of structural performance, economical efficiency and constructability. However, PSC girders have overtuning risk in construction in which extra work needs to protect. The low center of gravity girder (MPC girder) is more stable and easier to construct than the traditional PSC girder, which has tweaked end point and mono-tendon anchor. In this study, we evaluated the structural advantages in the deflection (slope) and stress on the link slab by using the finite element method. As a result, it was found that the reinforcement in the link slab for the bridge continuation may be reduced because of less displacement.
