Brugertype

Brugertype is a term used in civil engineering to classify a bridge according to its structural form, load path, and typical applications. It describes how the deck is supported and how forces are carried across the span, and it helps engineers compare design options for a given site and use.

Beam bridges, or girder bridges, are among the simplest and most economical for short spans. They consist of horizontal beams that transfer loads to vertical supports, and are commonly built in reinforced concrete or steel.

Arch bridges use a curved underside to carry loads primarily in compression. The arch transfers thrust to the abutments, allowing for elegant spans in stone, concrete, or steel.

Truss bridges employ a framework of interconnected triangles to distribute loads efficiently over longer spans. They are typically made of steel and are well suited to moderate to long crossing lengths.

Suspension bridges place the deck beneath a network of main cables suspended between towers, with hangers carrying the deck. They are favored for very long spans but require substantial foundations and maintenance.

Cable-stayed bridges use towers with cables connected directly to the deck, offering a balance between span length, construction effort, and cost. They are common for medium to long spans and can be built with various aesthetics.

Materials commonly used in Brugertype classifications include reinforced concrete, steel, timber, and composites. The choice affects strength, durability, maintenance, and visual impact, while the intended function—road, rail, or pedestrian use—guides the selection of form and detailing.
