Beam bridges are the most simple of structural forms being supported by an abutment at each end of the deck. No moments are transferred through the support hence their structural type is known as simply supported.
The simplest beam bridge could be a slab of stone or a plank of wood laid across a stream. Bridges designed for modern infrastructure will usually be constructed of steel or reinforced concrete, or a combination of both. The concrete used can either be reinforced, pre-stressed or post-tensioned.
Types of construction could include having many beams side by side with a deck across the top of them, to a main beam either side supporting a deck between them. The main beams could be I-beams, trusses or box girders. They could be half-through, or braced across the top to create a through bridge.
Examples of famous beam bridges include the East India Beam Footbridge and Canary Wharf Beam Bridge. There are not a huge amount of famous beam bridges because the majority of beam bridges are relatively unimpressive. Beam bridges are simple and cheap to construct so the majority of the time, they are constructed as a simple and cheap method to cross a river or stream. They are rarely built with the intention of being amazing architectural and artistic developments.
