A truss represents a structural system whose elements are two-force members arranged in a planar triangular pattern and each member is either in tension or compression. The stability of a truss relates to its triang… See more

The first step in designing a truss is the analysis of its stability, its internal and external determinacy or indeterminacy. Stability in trusses refers to their ability to maintain their configuration while resisting loads appli… See more

Space frames are three-dimensional trusses where members are in tension and compression only. By definition, true trusses should have pinned connections while frames have rigid joints. Space frames ma… See more

The economic depth-to-span ratio for steel trusses is 1:10 to 1:20, and for timber trusses is 1:6 to 1:10. The spacing of trusses in roof structures should be 20 to 30 ft for steel structures and 12 to 27 ft for timber trus… See more
