Curved bridges made of curved or straight beams, depending on the curvature.

Due to the type and width of the deck, box girders are used.

Use in isostatic and statically indeterminate set-ups.

Curved bridges with a constant radius, clothoids and straight sections.

They can be made with constant or variable depths.

• Demanding layouts with small curvature ratios.
• Depths from 0.80 to 2.20 m.
• Widths of 2.20 and 3.96 m.
• Spans between 20 and 42 m.
• Thanks to prefabrication, they can be made as simply and quickly as straight bridges.
• Excellent geometry due to placement of specific moulds for these elements (radii 50,120,160,200 m).
• For deck widths between 7.0 and 13.0 m.
• They are built with a single box girder.

For radii of over 200 m, the approximation along the straight beam, forming a polygonal shape affords excellent results.

For radii of less than 200 m, curved beams must be used.

Highway junctions.

Roundabouts on overpasses.

Bridges with unique features.

Typical arrangement with a single box girder cross-section.

Post-tensioned execution of the piece.

Cantilever support on 4 temporary or permanent points.

Double supports at each end.

Decks with variable depth slabs using permanent or temporary struts or a variable edge truss.

• Adapts to increasing demands with minimal radii.
• Avoids the cost of using costly, complex arch centres in the construction work.
• Simple deck construction, avoiding complex developments for incrementally launched and progressive cantilever bridges.
• Substantially shortens the construction period.
• High quality, rigid moulds are created, permitting excellent geometric shape of the piece.
