Bridge Substructure Engineering: Pier Cap Design, Elastomeric Bearings & Scour Depth

Anchoring Massive Transportation Loads Across River Crossings

Bridge superstructures rely entirely on robust substructures to transfer vehicle traffic loads safely down through riverbeds into solid underlying ground.

Substructure Design Considerations

Bridge engineers analyze hydraulic river forces, thermal expansion, and vehicular braking loads.

Pier Cap Cantilever Bending: Reinforcing heavy pier caps against punching shear from deck girder bearings.
Elastomeric Bearing Pads: Accommodating girder thermal expansion and contraction without damaging concrete supports.
Hydraulic Scour Depth: Placing foundation pile caps deep below riverbed erosion zones to avoid foundation exposure.
