Truss girder The bending and torsional bearing capacity is large, the structure is simple, and the construction is easy. The overall performance of the pipe truss structure is superior, the shape is beautiful, and the force of each member is clear, which is especially suitable for large-span space structures.
Truss girder in the truss structure refers to the truss beam, which is a latticed beam structure. Truss structures are often used in public buildings such as large-span workshops, exhibition halls, gymnasiums, and bridges.
·Truss girder is a plane or space structure with triangular elements generally composed of straight rods. The truss rods mainly bear the axial tension or pressure, so that the strength of the material can be fully utilized and the material can be saved. When the span is large, the material can be saved compared with the solid web beam. , reduce self-weight and increase stiffness.
Truss girder bridges are a form of bridges, generally found in railways and highways, and are divided into two types: upper chord and lower chord.
