1. A Truss bridge is a type of bridge whose main element is a truss, which is a structure of connected elements that form triangular units.
A truss is formed by many different beams that come together to form triangles to support the bridge’s way. Trusses are used to support and stabilize the bridge. A truss is a very rigid structure, and it transfers the load from a single point to a much wider area. It helps to handle compression, tension, and weight of the different types of loads.
The reason why the shape (truss) is so useful for building bridges is the fact that when it is placed under stress, the tension or compression created makes the structure stronger. This process makes it possible to support dynamic loads under variable conditions.
The key benefit of using a truss bridge to span a distance is that they are relatively lightweight, but can still be reinforced to provide strength. Because of the triangular design, each part of the bridge helps to support other parts, making it an effective design.
2. Truss bridges are formed with a structure of connected elements that form triangular structures to make up the bridge. Trusses are the triangles that connect to the top and bottom cord and two end posts.
The trusses make up reinforcement for the bridge that even the load-bearing across the structure. Furthermore, the truss dissipates the load through the structure so the middle of the beam experiences less compression and tension. As you will see later, there are several variations of the truss, but it starts with a top and bottom cord and a series of trusses.
