Warren Truss Roof

Trusses are cost effective.

Warren truss roof.

Trusses are cost effective. The internal diagonal members resist tension and compression forces alternately. This gives a pure truss. These triangles limit the force of the load to compression and tension of the bridge parts.

All trusses are designed to nationally recognized standards and building codes and supplied with engineered sealed drawings. Has been providing quality wooden roof and floor trusses at a competitive price since our founding in 1967. 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. All trusses are designed to nationally recognized standards and building codes and supplied with engineered sealed drawings.

It was invented by james warren and is now commonly used today. The warren truss consists of longitudinal members joined only by angled cross members forming alternately inverted equilateral triangle shaped spaces along its length. A metal plate connected wood truss is a roof or floor truss whose wood members are connected with metal connector plates. The warren truss dispenses with internal vertical members entirely and is formed from a series of equilateral triangles.

Truss members form a series of equilateral triangles alternating up and down. By eliminating the vertical members the warren truss is relatively economical in terms of material use. Warren trusses are commonly used in long span buildings ranging from 20 to 100 m in span. A modified warren truss may be adopted where additional members are introduced to provide a node at for example purlin locations.

Our knowledgeable design staff has over 85 years of combined experience. 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. The warren truss design uses equilateral triangles in the framework to spread out the load on the bridge. Each individual strut beam or tie is only subject to tension or compression forces there are no bending or torsional forces on them.

History of the truss bridge. Maximum floor joist span no. 2 grade of douglas fir and maximum span floor joists. Maximum span douglas fir in horizontal roof rafters and maximum span.

Truss members are made up of all equivalent equilateral triangles. Floor trusses facilitate the routing of plumbing electrical and hvac components within the floor system while maintaining aesthetic and functional specifications.
