Arch trusses are trellises shaped like an arch commonly used in bridge construction and some building designs. They come in various shapes and constructions, including the string arch truss. Some officials are implementing a tagging system for certain types of roof trusses to aid first responders. Engineers use CAD tools to provide the best truss design for a project. Examples of arch bridge architecture can be found online.
An arch truss is a trellis that includes the shape of an arch. These types of trusses are common in many different types of buildings. Traditional trellises are made from wood, but some types of trellises are also made from metal.
In residential work, trusses are used to support a roof. Residential construction rarely uses arched trusses, as the standard roof design is triangular. However, for domed buildings, an arched truss may be part of what an engineer uses to implement the design.
The arch truss is often used in bridge construction, where the truss may be wood (typically in older bridge designs) or metal. One major type of bridge design is an arch bridge, where the load on the bridge is deposited towards the supports at each end. Another common bridge style is a truss bridge, where triangular trusses bear the load on a bridge structure. An “arch truss bridge” is a combination of these two, where a number of triangular trusses can have an overall arch shape.
An arched structure can be useful in many different types of building designs. Typically, a bridge or other structure benefits from having a series of trusses arranged in an arc shape. The series of triangular trusses forms a single arch. This arch is uniquely designed to support a structure.
Arched trusses come in a variety of shapes and constructions. One of them is the string arch truss, where the trellises create a long, thin arc. The arched bowstring truss can cause specific challenges for those involved in structural or fire safety work.
To help first responders and others, some public works officials are looking to implement a tagging system for certain types of roof trusses. Others are examining the impact of beam design on bridge safety. Engineers are constantly evaluating truss styles to see how they can contribute to structural safety for a specific project. These professionals can use computer aided drafting (CAD) tools and other new technologies to provide the best truss design for a residential, commercial or public works project.
To learn more about the difference between an arch bridge and other types, Internet users can find many examples of this type of architecture online. Actual blueprints, diagrams, or photographs can help illustrate how the shape of the arch contributes to stability in these bridge designs. Similar styles can also be seen in outdoor walkways and other installations.
