Warren Truss Roof

Trusses are cost effective.

Warren truss roof.

The warren truss consists of longitudinal members joined only by angled cross members forming alternately inverted equilateral triangle shaped spaces along its length. A modified warren truss may be adopted where additional members are introduced to provide a node at for example purlin locations. The warren truss has equal length compression and tension web members and fewer members than a pratt truss. A metal plate connected wood truss is a roof or floor truss whose wood members are connected with metal connector plates.

All trusses are designed to nationally recognized standards and building codes and supplied with engineered sealed drawings. These triangles limit the force of the load to compression and tension of the bridge parts. Our knowledgeable design staff has over 85 years of combined experience. Maximum span douglas fir in horizontal roof rafters and maximum span.

Maximum floor joist span no. Warren trusses are commonly used in long span buildings ranging from 20 to 100 m in span. History of the truss bridge. The warren truss dispenses with internal vertical members entirely and is formed from a series of equilateral triangles.

Warren truss company inc. 2 grade of douglas fir and maximum span floor joists. All trusses are designed to nationally recognized standards and building codes and supplied with engineered sealed drawings. Using the latest in 3d software our designers can produce truss profiles that satisfy virtually any aesthetic and functional specification.

A warren truss bridge is an important structure and the warren truss bridge design is commonly used in bridge construction because it will carry a tremendous load. Truss members are made up of all equivalent equilateral triangles. Truss members form a series of equilateral triangles alternating up and down. The internal diagonal members resist tension and compression forces alternately.

Trusses are cost effective. By eliminating the vertical members the warren truss is relatively economical in terms of material use. It was invented by james warren and is now commonly used today. This gives a pure truss.

In the image given above the upper and lower horizontal parts are in tension along with the diagonals in the center while the outer diagonals are compressed. The warren truss design uses equilateral triangles in the framework to spread out the load on the bridge.
