Trusses are an essential component of many structures, including bridges, buildings, and even roller coasters. They design to provide support and stability to the structure they attach to and come in a wide variety of shapes and sizes to suit different needs. In this article, we’ll take a closer look at some of the different types of trusses that commonly use in construction.types of trusses
King post truss
The king post truss is one of the oldest and simplest types of trusses. It consists of a single vertical post, called the king post, that supports a horizontal beam at the top, and two angled beams called the rafters, that support the roof. King post trusses commonly use in smaller structures, such as sheds and garages.
Queen post truss
The queen post truss is similar to the king post truss, but instead of a single vertical post, it has two vertical posts, called queen posts, that support the horizontal beam at the top. Queen post trusses are more stable thanking post trusses and are often use in larger structures, such as barns and homes.types of trusses
Pratt truss
The Pratt truss is a common type of truss use in bridges and buildings. It consists of diagonal members that slope towards the center of the span, and vertical members that support the weight of the structure. The Pratt truss often used in longer spans, as it is strong and lightweight.
Warren truss
The Warren truss is another common type of truss use in bridges and buildings. It consists of diagonal members that slope in opposite directions, creating a zigzag pattern. The Warren truss often use in shorter spans, as it is very strong and rigid.
Howe truss
The Howe truss is a type of truss that is similar to the Pratt truss, but with the diagonal members sloping in the opposite direction. It often uses in longer spans, as it is strong and rigid, and can use in both bridges and buildings.
Bowstring truss
The bowstring truss is a type of truss that often use in larger buildings, such as gymnasiums and airplane hangars. It consists of an arched top chord and a straight bottom chord, with diagonal members connecting the two chords. The bowstring truss design to distribute weight evenly and is often use in structures with a wide span.
Scissors truss
The scissors truss is a type of truss that is commonly use in homes and other residential structures. It consists of two angled members that cross in the center, creating a triangular shape. The scissors truss often use in roof designs, as it allows for more headroom and creates a larger living space in the attic.
Fink truss
The Fink truss is a type of truss that is commonly use in residential and commercial buildings. It consists of diagonal members that slope towards the center of the span, and a horizontal member at the bottom that connects the diagonal members. The Fink truss often use in shorter spans, as it is lightweight and cost-effective.
K truss
The K truss is a type of truss that is commonly use in bridges and other structures that require a wide span. It consists of two diagonal members that slope in opposite directions, and a vertical member that connects the two diagonals in the center. The K truss designed to distribute weight evenly and is often use in structures with a wide span.
Vierendeel truss
The Vierendeel truss is a type of truss that is often use in buildings and other structures where a strong and rigid frame require. It consists of vertical and horizontal members that form a grid-like pattern, with no diagonal members. The Vierendeel truss design to resist bending and twisting forces, making it ideal for use in buildings with large windows or other openings.
Lattice truss
The lattice truss is a type of truss that is often use in bridges and other structures where a lightweight yet strong frame require. It consists of diagonal and vertical members that are connected together in a lattice-like pattern. The lattice truss often uses in longer spans, as it is strong and lightweight.
Barrel vault truss
The barrel vault truss is a type of truss that often use in architectural structures, such as churches and other historical buildings. It consists of a series of curved members that create a barrel-like shape. The barrel vault truss is designe to support heavy loads and often use in structures with large open spaces.
Parallel chord truss
The parallel chord truss is a type of truss that often use in industrial and commercial buildings. It consists of two horizontal members, called the top and bottom chords. They are parallel to each other, with diagonal members connecting the two chords. The parallel chord truss design to support heavy loads and is often use in structures with a wide span.
Pratt pony truss
The Pratt pony truss is a type of truss that often use in shorter spans. Such as footbridges and pedestrian walkways. It consists of diagonal members that slope towards the center of the span, and vertical members that support the weight of the structure. The Pratt pony truss is lightweight yet strong and often use in structures that require a simple and cost-effective design.
Modified Warren truss
The modified Warren truss is a type of truss that often use in longer spans. Such as bridges and industrial buildings. It is similar to the Warren truss, but with additional vertical members that support the weight of the structure. The modified Warren truss is designed to be strong and rigid and is often use in structures with a wide span.
In conclusion
Trusses come in a variety of shapes and sizes, each with its own unique advantages and disadvantages. When designing a structure. It’s important to consider the specific needs of the project and select the appropriate truss type based on those needs. By selecting the right truss type, builders can ensure that their structures are strong, stable, and safe.
