Which pier type often frames into a continuous cap?

The correct choice frames into a continuous cap, facilitating the connection of multiple sections of the bridge. A pile bent typically consists of vertical piles driven into the ground or underwater that support a horizontal cap. The design allows for adequate load distribution from the superstructure of the bridge to the foundation.

In addition to structural integrity, this design is efficient for construction over varying soil conditions and can handle significant lateral forces, making it suitable for supporting spans in bridge construction. By integrating into a continuous cap, pile bents create a solid foundation for the deck, ensuring stability and durability over time.

Other pier types may not provide the same connections or load distribution characteristics as pile bents. For instance, cantilever piers may extend outwards without the same cap integration, and open bents, although used in certain contexts, do not typically feature a continuous cap as prominently as pile bents. Drilled shafts serve a purpose in deep foundations but operate differently in terms of upper structure support. Therefore, the critical action of framing into a continuous cap aligns specifically with the functionality and design of pile bents.
