Aohong spherical bridge bearing allow for thermal, seismic and mechanical expansion and contraction. They also provide multidirectional rotation for highway bridges, railway bridges and other civil engineering structures.
Custom Engineered
Aohong spherical bridge bearing are all custom engineered to meet the specified requirements of the structure efficiently. They are also designed, fabricated, tested and inspected to meet ASTM, AASHTO, AREMA or other specified standards.
Aohong offers three types of spherical bearings:
- Fixed
- Guided expansion
- Non-guided expansion
Aohong spherical bridge bearing consist of a concave bearing plate, a convex mating plate, an upper sole plate and a lower masonry plate. Sliding surfaces consist of bonded PTFE mated to highly polished stainless steel. Either woven PTFE or sheet PTFE may be used depending on a project’s requirements.
Main technical performance
- Spherical bearing vertical loading capacity (kN): 1000, 1500, 2000, 2500, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000, 12500, 15000, 17500, 20000.
- Design displacement of spherical bearing
- Bridge in longitudinal direction
1000 - 2500 kN e = ±50 mm e = ±100 mm.
3000 - 20000 kN e = ±50 mm e = ±100 mm e = ±150 mm.
- Bridge in transverse direction
Free sliding spherical bearing e = ±40 mm.
The design displacement can be customized according to the project requirements).
