Product Description
Steel structure bridges are bridges constructed primarily using steel materials for their structural components. These bridges are known for their strength, durability, and versatility. Steel offers several advantages for bridge construction:
Strength: Steel is renowned for its high strength-to-weight ratio, making it ideal for spanning long distances without requiring excessive support columns or piers.
Durability: Steel is resistant to corrosion, especially when properly coated or treated. This makes steel bridges suitable for various environmental conditions, including coastal areas where exposure to saltwater is a concern.
Versatility: Steel can be fabricated into various shapes and sizes, allowing engineers to design bridges to accommodate different spans, traffic loads, and architectural styles.
Speed of construction: Steel structures can be prefabricated off-site, allowing for faster construction times compared to traditional concrete bridges. This is particularly advantageous for minimizing traffic disruptions during bridge construction.
Maintenance: Steel bridges generally require less maintenance than other types of bridges. Routine inspections and occasional repairs are typically sufficient to maintain their structural integrity over their lifespan.
About steel structure bridge Steel bridge, the main bearing structure of the rigid bridge. The beam and the leg or pier (platform) body form a rigid connection. Because of the consolidation of the pier beam, the whole beam and pier are stressed. 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 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 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.
