The plate designed to prevent a beam from disconnecting from its bearing is called what?

• A. Bearing Plate
• B. Keeper Plate
• C. Anchor Bolt
• D. Tie Plate

Answer: (B)

Identifying the component that keeps a beam from pulling away from its bearing is about understanding how bridges are kept securely seated at supports. A keeper plate is a small plate placed at the end of a beam on its bearing seat to act as a stop, preventing the beam from sliding off or disconnecting under load. It ensures the beam remains aligned and attached to the bearing system when forces are applied, especially during moments of reversal or uplift. This role is distinct from a bearing plate, which mainly distributes load between the beam and bearing and allows rotation; an anchor bolt, which secures components to the foundation; and a tie plate, which is used in railway track construction. Therefore, the plate designed to prevent disconnection from the bearing is the keeper plate.
