Steel Trusses
Triangulated members spanning long distances with low self-weight — roofs, transfers and bridges.
Technical Overview
Trusses carry load primarily through axial forces in chords and web members. Depth-to-span ratio, node detailing and transport splitting are key decisions.
Applications
- Long-span roofs
- Transfer structures
- Pedestrian bridges
- Hangars and halls
Engineering Considerations
- Chord buckling and lateral restraint
- Node eccentricity and secondary moments
- Camber and deflection
- Splice locations for transport
Fabrication Considerations
- Trial assembly may be required for complex trusses
- Shop welding of nodes improves quality
