Product Definition

• Curved bridges made of curved or straight beams, depending on the curvature.
• Increasing demands with minimal radii. Tendency to use curved beams.
• Due to the type and width of the deck, box girders are used.

Main Characteristics

• Demanding layouts with small curvature ratios.
• Depths from 1.0 to 2.0 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.

Types Of Structures Where It Can Be Used

• Use in isostatic and statically indeterminate set-ups
• Made with box girders
• They can be made with constant or variable depths.
• For deck widths between 7.0 and 13.0 m.
• They are solved with only one box girder, with a lower width of 3.30 or 3.96 m.

Main Applications

• 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.
• Beams with radii between 50 and 200 m are made.
• So far, Pacadar has achieved curved beams with span lengths over 40 m.

Advantages

• 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.

Construction Details

• Typical arrangement with a single box girder cross-section.
• Box lower width of 3.30 or 3.96 m.
• Most common span length between supports is from 20.0 to 35.0 m.
• For deck widths between 7.0 and 12.0 m.
