How Does a Truss Work?

A truss is a series of individual members, acting in tension or compression and performing together as a unit. On truss bridges, a tension member is subject to forces that pull outward at its ends. Even on a “wooden” truss bridge, these members are often individual metal pieces such as bars or rods.

How Does a Truss Work?

A truss is an important architectural element used in building construction, roofing, and in bridges. It is a rigid framework of interconnected beams that is designed to support a load, such as a roof or bridge deck. Trusses are usually made from steel, aluminum, or wood, although other materials may be used. They are typically made in a triangular formation, although they can also be constructed in other shapes. The purpose of a truss is to create a structure that can resist bending and twisting forces, while also remaining lightweight and economical.

The basic concept behind trusses is simple. All of the beams are arranged in a triangular pattern, with each beam connected to its two adjacent beams. This creates a structure that is incredibly strong and rigid, yet also lightweight, since the beams are not actually touching each other. The strength of the truss comes from the fact that each beam is connected to its two adjacent beams, creating a triangular shape that resists bending and twisting forces.

Trusses are usually constructed from a variety of materials, such as wood, steel, and aluminum. The most common type of truss is made from steel, as it is strong and durable, and is also relatively inexpensive. Aluminum trusses are also
