Types of Girders

Arch Bridge
Arch Bridge

A girder bridge, in general, is a bridge that uses girders as the means of supporting the deck. A bridge consists of three parts: the foundation (abutments and piers), the superstructure (girder, truss, or arch), and the deck.

Bascule Bridge
Bascule Bridge

A bascule bridge (sometimes referred to as a drawbridge) is a moveable bridge with a counterweight that continuously balances a span, or "leaf", throughout its upward swing to provide clearance for boat traffic.

Beam Bridge
Beam Bridge

Generally in construction industry large beams are referred as girders. There is no hard and fast rule for dimensions that decide when a beam is actually a girder. Instead, structural engineers look mainly at how the component is used. If it is the chief horizontal support in a structure, it is a girder, not a beam.

Box Girder Bridge
Box Girder Bridge

A box girder bridge is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section.

Cable-Stayed Bridge
Cable-Stayed Bridge

The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range where cantilever bridges would rapidly grow heavier if the span were lengthened, while suspension bridge cabling would not be more economical if the span were shortened.

Canopy Bridge
Canopy Bridge

A girder bridge is very likely the most commonly built and utilized bridge in the world. Its basic design, in the most simplified form, can be compared to a log ranging from one side to the other across a river or creek. In modern girder steel bridges, the two most common shapes are plate girders and box-girders.
