The truss bridge has been around for literally centuries and is a load-bearing structure which incorporates a truss in a highly efficient yet very simple design. Example of a Beam Bridge: Iowa River bridge. There is no transfer of stress which you see in arch structures and other types of bridges. This is often referred to as a “simply supported” structure. The area over which people or vehicles travel will be a simple decking positioned vertically across the underlying beams. Very often you will find other beams, positioned in between the main beams, offering additional support and stability. These are supported either side by two beams running between abutments/piers. The deck area traditionally consists of wood plank or stone slabs (often referred to as a clapper bridge). A perfect example being a basic log bridge – something you may see while out on a country walk. Types of bridges The 7 main types of bridges are:Ī beam bridge is one of the simplest types of bridge. We will now take a look at the different types of bridges and how they work. Many of the world’s greatest engineers have failed to add any significant improvements to the basic load-bearing designs of years gone by. One interesting factor when looking at different bridge designs is their longevity and the fact they have been around for centuries. There are also designs that transmit tension through bridge cables which allow a degree of flexibility for different terrains. In some cases the deck area will be the load-bearing element while in others it will be the towers. The way in which the vertical/horizontal stresses are managed dictates the structure of different bridges. ![]() There are 7 main types of bridges: Arch Bridge, Beam Bridge, Cable-stayed Bridge, Cantilever Bridge, Suspension Bridge, Truss Bridge, Tied Arch Bridge. What is the most common type of the bridge?.What is the most expensive type of bridge to build?.
