What is the main function of roller bearings in a bridge structure?

What type of support settlement can be controlled by bridge bearings?

Pin bearings allow rotational movement, accommodating angular displacements in bridge structures.
The primary function of bridge bearings is to transfer loads and movements between the bridge superstructure and substructure while allowing for necessary flexibilities.
Rocker bearings, designed with a curved surface, can accommodate translational movements hence facilitating horizontal adjustments during load variations.
Roller bearings consist of cylindrical rollers that facilitate horizontal movement, reducing friction and wear.

Recent bridge bearings incorporate seismic protection features that help absorb and dissipate energy during earthquakes, enhancing the structure's resilience.

Bridge bearings transfer vertical and horizontal loads from the superstructure to the substructure, ensuring structural stability.
Bridge bearings help control support settlement, allowing for adjustments in response to ground movement or structural loads.

Unlike roller bearings, pin bearings do not allow translational movement; they mainly provide rotational freedom.
Roller bearings actively reduce friction to facilitate smooth movement across joints in a bridge structure, while pin bearings focus primarily on rotation.

The main purpose of existing bridge bearings is to ensure safety and durability by managing forces and movements effectively across the bridge system.
