To determine orientation of guided bearings, one have to understand movement of curved region of a pre-stressed bridge. Movement of pre-stress and creep are tangential to curvature of the bridge or along longitudinal axis, though movement due to temperature and shrinkage effects are in a direction towards fixed pier. If direction of guided bearings is associated towards fixed bearing in the abutment, the main difference in direction of pre-stress and creep movement and guided direction towards fixed bearing would generate a locked-in force in bridge system. The magnitude of lock-in force is dependent on stiffness of deck and supports. If a force is small, it can be designed as added force acting on support and deck. However, if force is large, temporary freedom of movement at guided bearings has to be provided throughout construction.
