A hinged arch bridge is one with hinges incorporated into its structure to allow movement. The most common varieties are the two-hinged bridge with hinges at the springing points and the three-hinged bridge with an additional hinge at the crown of the arch. Hinges at the springing point prevent bending moments from being transferred to the bridge abutments. A triple-hinged bridge is statically determinate, while the other versions are not.
The hinged arches involve three hinge arrangements: single-hinged type, two-hinged type, and three-hinged type. In arch bridges, two hinges or three hinges are frequently used. The two-hinged arch has pins at the end bearings, so that only horizontal and vertical components of force act on the abutment. The two-hinged arch is most often used to bridge long spans. The three-hinged arch has a hinge at the crown as well as the abutments, making it statically determinate and eliminating stresses due to change of temperature and rib shortening. In addition, the less complex forces on the bases can simplify the foundation design. Three-hinged arch also has obvious drawbacks. For example, three-hinged arch bridges have smaller rigidities and therefore experience much more deflection. In addition, the hinges are complex in fabrication. Steel arch bridge can be built as either hingeless (fixed) or hinged.
About Us
We always use high-quality structure steel in certified grades. Prefabrication of steelwork in our highly controlled factory conditions leads to high quality work at minimum cost. The excellent quality control is achieved through a thorough testing regime at the steel mills and during the fabrication processes of cutting and drilling, assembly, welding, and protective treatment. The quality assurance that is attained should give confidence to all clients and engineers who specify steel for their bridge project.
We will use Corten Steel for most type of bridges. Corten steel is a high strength low alloy steel that in suitable environments forms an adherent protective rust ‘patina’, to inhibit further corrosion. The corrosion rate is so low that bridges fabricated from unpainted weathering steel can achieve a 120 year design life with only nominal maintenance.
