AWM Table: | Bridges, Bridge Span |
Attribute: | Superstructure Long Section |
Purpose: | To provide superstructure categorisation that differentiates the span and support provided by the longitudinal section of the bridge, as opposed to the cross section. |
Value | Description | Photo Example |
---|---|---|
Arch, Deck | Abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side, and partially into a vertical load on the arch supports. | ![]() |
Arch, Earth Filled | Earth filled arches support the roadway on earth fill that is contained between the spandrel walls. | ![]() |
Arch, Through | Bridge in which the base of an arch structure is below the deck but the top rises above it. | ![]() |
Continuous Span | A superstructure which extends as one piece over multiple supports. | ![]() |
Hinged Span | A hinged bridge span is a bridge with a hinge that allows the bridge to move or be lifted. | ![]() |
Integral Span | An integral bridge is a structure where there are no expansion joints in the superstructure between spans and between spans and abutments. | ![]() |
Portal Frame | The portal frame bridge system comprises of a precast portal frame which interlinks on precast structural base sections. A joint is created between the frame and the base units. | ![]() |
Semi-Integral (Link Slab Over Pier) | A semi-integral span bridge with a link slab over a pier is a bridge design that uses link slabs to connect bridge decks without traditional deck joints. | ![]() |
Simple Span | Simple span bridges cross from one support to another and can be joined together to create a longer span. | ![]() |
Suspended Span | Span in which the arms do not meet in the center; instead, they support a central truss bridge which rests on the ends of the cantilever arms. | ![]() |
Suspension | A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. | ![]() |
