Warren Truss Roof

By eliminating the vertical members the warren truss is relatively economical in terms of material use.

Warren truss roof.

Truss members form a series of equilateral triangles alternating up and down. A metal plate connected wood truss is a roof or floor truss whose wood members are connected with metal connector plates. Maximum span douglas fir in horizontal roof rafters and maximum span. Trusses are cost effective.

Floor trusses facilitate the routing of plumbing electrical and hvac components within the floor system while maintaining aesthetic and functional specifications. 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 dispenses with internal vertical members entirely and is formed from a series of equilateral triangles. It was invented by james warren and is now commonly used today.

All trusses are designed to nationally recognized standards and building codes and supplied with engineered sealed drawings. The warren truss has equal length compression and tension web members and fewer members than a pratt truss. The warren truss design uses equilateral triangles in the framework to spread out the load on the bridge. These triangles limit the force of the load to compression and tension of the bridge parts.

Has been providing quality wooden roof and floor trusses at a competitive price since our founding in 1967. Using the latest in 3d software our designers can produce truss profiles that satisfy virtually any aesthetic and functional specification. Trusses are cost effective. Our knowledgeable design staff has over 85 years of combined experience.

Each individual strut beam or tie is only subject to tension or compression forces there are no bending or torsional forces on them. The warren truss consists of longitudinal members joined only by angled cross members forming alternately inverted equilateral triangle shaped spaces along its length. Maximum floor joist span no. This gives a pure truss.

History of the truss bridge. A modified warren truss may be adopted where additional members are introduced to provide a node at for example purlin locations. 2 grade of douglas fir and maximum span floor joists. Warren trusses are commonly used in long span buildings ranging from 20 to 100 m in span.

Truss members are made up of all equivalent equilateral triangles. All trusses are designed to nationally recognized standards and building codes and supplied with engineered sealed drawings.
