What is the composition of roller bearings?
One or more rollers between two parallel steel plates
What type of forces do bridge bearings transfer between the bridge superstructure and substructure?
Traffic and dead loads
What is the primary function of a pin bearing in a bridge structure?
Permits rotational movement and prevents longitudinal movement
Which type of bridge bearing contains a curved surface to accommodate translational movements?
Hinged rocker bearing
What is the purpose of roller bearings in a bridge structure?
Facilitate both translations and rotations
What seismic protection feature do recent bridge bearings act as?
Energy dissipators during earthquakes
How do roller bearings differ from pin bearings in a bridge structure?
Roller bearings permit both rotational and translational movements, while pin bearings permit only rotational movement
What is the function of a rocker bearing in a bridge structure?
To contain a curved surface that accommodates the translational movements
What is the primary purpose of existing bridge bearings?
To accommodate and transfer dynamic forces and vibrations without causing wear or destruction to the substructure
What is the main function of roller bearings in a bridge structure?
To facilitate both rotations and translations in the longitudinal direction
What type of support settlement can be controlled by bridge bearings?
Vertical support settlement
