Hot Rolled H-beam Steel Structure Beam And Column Structure Steel H-beam Price of Low-cost and Widely Used Long-span Steel Structures for Bridge Construction

Bridge Steel bridge, the main bearing structure of the rigid structure of the bridge. The beam and the leg or pier (platform) body form a rigid connection. Due to the consolidation of pier beams, the whole beam and pier are stressed, and the pier not only bears the vertical pressure caused by the load on the beam, but also bears the bending moment and horizontal thrust.
The structure can be divided into portal rigid frame bridge, inclined leg rigid frame bridge, T-shaped rigid frame bridge and continuous rigid frame bridge. The main beam of steel structure bridge generally needs to bear positive and negative bending moments, and the cross section should adopt box section. The force of the main beam of continuous steel structure bridge is basically the same as that of continuous beam, and the cross section form and size are basically the same as that of continuous beam.
