How can special bearings for highway bridges withstand vehicle loads
2026-04-07The core mechanism of special bearings for highway bridges (pot type, spherical, seismic isolation, anti pull, etc.) to bear vehicle loads is: vertical rigid bearing+horizontal flexible adaptation+dynamic buffering energy dissipation, which smoothly, uniformly, and controllably transmits the vertical pressure, braking/centrifugal horizontal force, and impact vibration of the vehicle to the pier.

What are the applications of spherical bearings on wide bridges in railway rail transit bridges
2026-03-02The application of spherical bearings on wide railway rail transit bridges (with large bridge deck width and complex lateral stress) relies on their universal rotation, bidirectional displacement, uniform force transmission, and high load-bearing characteristics to solve key problems such as lateral deformation coordination, multi-directional displacement, and uniform load distribution of wide bri
-
Where are high damping isolation rubber bearings mainly used for highway bridges
2026-02-24High damping isolation rubber bearings (HDR) for highway bridges are mainly used in high-intensity earthquake zones, cross fault zones, large-span and urban key bridges. The core is to provide integrated protection of isolation, energy dissipation and load-bearing between the beam and the pier.
