Roof Truss Lattice Girder Truss

These are found in industrial buildings drawing rooms and large spaces with a span of 20 30 meters.

Roof truss lattice girder truss.

North light roof truss have a wide set of lattice girders that include support trusses. It was developed in ireland as a wide span shallow rise roof truss for industrial structures. North light truss is the oldest and most economical kind of truss. The belfast truss is a cross between the town s lattice truss and the bowstring truss.

Mctear co of belfast ireland began fabricating these trusses in wood starting around 1866. Girder trusses are designed to carry additional loads other than standard roof loads. Using these structures in roof design eliminates the need for a load bearing wall below resulting in open floor plans. The terms are generally applied to the planar truss.

Girders may also be designed to accommodate special applications or designs. The truss or lattice girder is a triangulated framework of members where loads in the plane of the truss or girder are resisted by axial forces in the individual members. These loads can be other trusses that attach by sitting on top of the girder or they may attach to the side of the girder using truss hangers. Space frame is formed when the members lie in three dimensions.

Buildings constructed in l or t shapes use girder truss systems where the roof changes direction.
