Viscous fluid damper is an energy-consuming damping equipment which has cylinder type structure filled with damping medium.
Viscous fluid damper is mainly used in bridges in area with frequent earthquakes and typhoon.
Producing damping effect by driving internal medium to flow through reciprocating motion of piston, and further making kinetic energy changed into thermal energy.
Bridge Expansion Joint
Modular expansion joint is a mechanical device installed in bridge expansion joint openings.
Rubber waterstop is manufactured from natural rubber and synthetic rubbers with many additives and fillers.
provide flexible movements and rotations between the superstructure and supporting structures to transfer whether horizontal or vertical force safely.
BAOLI bridge bearings are suitable for any type of structure, especially for large loads and rotation wide bridge and curved bridge. Standard: EN 1337, AASHTO, BS 5400 or AS 5100
