Bent Cap
Bent cap, also known as cap beam, is a transverse load-bearing component installed on the top of bridge piers, arranged between piers and upper beam slabs for force transmission. It is generally of reinforced concrete structure and cast-in-situ with steel formwork at the construction site.

Product Description
Bent Cap, also known as a cap girder, is a horizontal load-bearing member located at the top of a bridge pier. Positioned between the pier and the superstructure beams and slabs, it serves as a critical link between the two. It is typically constructed of reinforced concrete and is cast in place using steel formwork.
Main Functions
1. Connect and secure multiple piers to enhance the structural integrity and lateral stability of the bridge substructure.
2. Directly support superstructure elements such as T-beams, box girders, and hollow-core slabs, evenly distributing the deck load to the underlying piers and foundations.
3. Adjust the position and elevation of the superstructure beams to ensure their stable placement and improve the overall load-bearing performance of the bridge.
Structural Characteristics
• Most have rectangular, trapezoidal, or vase-shaped cross-sections, featuring a simple design and clear load-bearing characteristics.
• Spans are typically short, but high resistance to bending and shear is required.
• They are integrally connected to the piers, providing high stiffness and structural integrity.
• Dimensions can be flexibly designed based on the bridge width, span length, and number of piers.
Advantages
1. Rational Load Distribution: Effectively disperses superstructure loads, ensuring uniform stress distribution across piers and improving bridge safety.
2. High Structural Integrity: Connects multiple independent piers into a single unit, enhancing the bridge’s resistance to lateral displacement, seismic activity, and wind loads.
3. Convenient Construction: Utilizes prefabricated steel formwork, which is easy to install and dismantle, resulting in high-quality concrete finishes.
4. Wide Applicability: Suitable for various bridge types, including highway bridges, railway bridges, elevated bridges, and municipal bridges.
5. Excellent Durability: The reinforced concrete structure is robust and durable, resulting in low long-term maintenance costs.
Applications
Widely used in various types of bridge engineering, it is a standard component for small- and medium-span bridges, elevated expressways, interchanges, and municipal bridges. It is particularly indispensable in bridges with multiple piers and serves as a critical component of the bridge substructure.
