Fish belly type longspan vierendeel truss structure
The invention discloses a fish belly type longspan vierendeel truss structure which comprises upper chords, lower chords and a plurality of flaky web members, wherein the upper chords and the lower chords are arranged in the up and down manner, and the upper and lower chords and the flaky web members are rigidly connected to form an integral truss; the upper and lower chords are made from at least two pieces of closed section steel; the upper chords are located on a same horizontal plane and are supported and connected by horizontal upper chord supporting rods; the lower chords are in downward protruding arc-shapes; the flaky web members are annular. No diagonal web members are arranged, so that the structure is concise in shape; the plane is not limited to be linear and can be an arc-shaped, so that the modeling requirement can be realized well; the upper and lower chords are made from the structural steel which is combined with the rigid flaky web members, so that integral torsion can be effectively prevented to prevent overturn; the web members are rigidly connected with the chords, so that the structure has the relatively good redundancy; the vertical plane is in a fish belly shape, so that the structure meets a bending moment distribution rule, is reasonable in stress, has the relatively good rigidity and stability and is suitable for steel structures such as longspan overbridges, and corridors.
