The terms are generally applied to the planar truss.
Roof truss lattice girder truss.
Space frame is formed when the members lie in three dimensions.
The main uses are.
North light truss is the oldest and most economical kind of truss.
It was developed in ireland as a wide span shallow rise roof truss for industrial structures.
North light roof truss have a wide set of lattice girders that include support trusses.
Girder trusses are designed to carry additional loads other than standard roof loads.
Buildings constructed in l or t shapes use girder truss systems where the roof changes direction.
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 are found in industrial buildings drawing rooms and large spaces with a span of 20 30 meters.
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.
Girders may also be designed to accommodate special applications or designs.
A girder truss is designed to support other secondary roof supports.
