A truss is a structure that consists of a series of triangles connected together. The triangles are arranged in such a way that the forces acting on them are transferred to the ground in a safe and efficient manner. Trusses are used in a variety of applications, including bridges, roofs, and towers. Trusses are a very efficient way to support large loads. This is because the weight of the load is distributed evenly across all of the members of the truss. This reduces the stress on each member, which makes the truss much stronger than a solid beam of the same size.

The history of the truss can be traced back to the early Bronze Age, around 2500 BC. The first trusses were built of timber and were used in primitive lake dwellings. The Greeks and Romans also used trusses in their architecture, and trusses became more common in Europe during the Middle Ages. In the early 19th century, trusses began to be used in bridges and other structures in the United States. Trusses are a versatile and efficient structural system that has been used for centuries to create strong, lightweight, and affordable structures.

What are the elements of a truss?

The elements of a truss are the chords, web members, and joints. The chords are the top and bottom horizontal members of the truss, and the web members are the vertical and diagonal members that connect the chords.

What causes a truss to fail?

A truss can fail due to a number of factors, including improper loading or overloading, high winds, and deterioration. It is important to inspect trusses regularly for signs of damage or deterioration. If any problems are found, they should be repaired immediately to prevent a failure.

Is a truss in tension or compression?

Truss triangles are arranged in such a way that the forces acting on them are always in tension or compression depending on the forces acting on them. In general, the members that are located on the top chords of a truss are in tension, while the members that are located on the bottom chords are in compression. The members that connect the top and bottom chords are in both tension and compression. The forces acting on a truss can be determined by analyzing the forces at each joint.

Truss - Fink, Double
Scale illustration of Double Fink Truss compared to other truss configurations

A double Fink truss is a type of roof truss that is made up of two sets of parallel chords that are connected by a series of diagonal members. The diagonal members are arranged in a triangular pattern, and the chords are sloped to form a triangular roof. Double Fink trusses are typically used for buildings with large spans, such as warehouses and factories. They are also used for some residential homes, especially those with large open floor plans.

The Double Fink Truss is configurable in a range of sizes with typical spans between 22’-60' (6.7-18.3 m) and overall heights of 3’8”-30’ (1.12-9.14 m). The thickness of wood trusses is commonly 1.5”, 3”, or 4.5” (3.8, 7.6, 11.4 cm). Trusses have a pitch ratio typically between 1:1 to 1:6.

Truss - Flat, Howe
Style and size comparison drawing of Flat Howe Truss compared to other truss types

A Howe flat truss is a type of truss that is used to support roofs and bridges. It is made up of a series of triangular panels that are connected by web members. The diagonal members of a Howe flat truss angle towards the center of the top chord, while the vertical members are in tension. This type of truss is very efficient in terms of weight and strength, making it a popular choice for a variety of applications.

The Flat Howe Truss is configurable in a range of sizes with typical spans between 24’-72’ (7.3-21.9 m) and overall heights of 1’4”-9’ (.41-2.44 m). The thickness of wood trusses is commonly 1.5”, 3”, or 4.5” (3.8, 7.6, 11.4 cm).

Truss - Dual Slope
Scale illustration of Dual Slope Truss compared to other truss configurations

A dual slope truss is a type of roof truss that has two different slopes. This type of truss is often used in buildings with large open spaces, such as warehouses or barns. Dual slope trusses are made up of a series of triangles that are connected together by web members. The triangles provide strength and support, while the web members help to distribute the weight of the roof evenly. Dual slope trusses are a versatile and efficient way to create a strong and durable roof.

The Dual Slope Truss is configurable in a range of sizes with typical spans between 16’-46’ (4.9-14 m) and overall heights of 2’8”-23’ (.81-7 m). The thickness of wood trusses is commonly 1.5”, 3”, or 4.5” (3.8, 7.6, 11.4 cm). Trusses have a pitch ratio typically between 1:1 to 1:6.

Truss - Bowstring
Style and size comparison drawing of Bowstring Truss compared to other truss types

A bowstring truss is a type of truss that has a curved top chord and a flat bottom chord. The curved top chord is under compression, while the flat bottom chord is under tension. The truss is held together by a series of diagonal struts and ties. Bowstring trusses are often used in roofs and bridges, as they can span long distances without the need for additional support.

The Bowstring Truss is configurable in a range of sizes with typical spans between 30’-60’ (9.1-18.3 m) and overall heights of 5’-30’ (1.52-9.14 m). The thickness of wood trusses is commonly 1.5”, 3”, or 4.5” (3.8, 7.6, 11.4 cm). Trusses have a pitch ratio typically between 1:1 to 1:6.

Truss - Flat, Sloping
Scale illustration of Sloping Flat Truss compared to other truss configurations

A sloping flat truss is a type of truss that has both top and bottom chords that are sloped equally. This makes the depth of the truss the same throughout its length. Sloping flat trusses are typically used in buildings with large open spans, such as warehouses, arenas, and churches. They can also be used to create a sloping ceiling in a room. Sloping flat trusses are made from wood or steel and are typically prefabricated in a factory. They are then assembled on site and installed.

The Sloping Flat Truss is configurable in a range of sizes with typical spans between 24’-72’ (7.3-21.9 m) and overall heights of 6’1”-44’8” (1.86-13.6 m). The truss depth of the Sloping Flat Truss is between 24”-72” (61-183 cm) with common wood truss thicknesses of 1.5”, 3”, or 4.5” (3.8, 7.6, 11.4 cm). Trusses have a pitch ratio typically between 1:1 to 1:6.
