Steel structure truss is a lattice structure system composed of steel components connected by nodes. It has the characteristics of light weight, high strength, large span and flexible shape. It is widely used in large-span buildings such as industrial plants, stadiums, bridges, airport terminals, etc.
Basic components of trusses:
Main components: upper chord, lower chord, web (diagonal and vertical), node plate (or directly welded/bolted).
Material: Usually low-alloy high-strength steel such as Q235 and Q345 is used, which has both plasticity and toughness.
Truss features:
1. High strength: Steel has excellent tensile and compressive properties, suitable for large-span structures.
2. Lightweight: Compared with concrete structures, it has light weight and small foundation load.
3. Industrialized construction: prefabrication in the factory, on-site assembly, and short construction period.
4. Flexible shape: It can be designed into various forms such as triangle, trapezoid, arch, etc.
