Description
The bridge bearing has been certified CE certificate by
European Notified Body. Therefore, our products are in copliance
with the European norm of EN ***7(structural bearings).

DESIGN
HORIZONTAL LOAD:
For free direction of fixed
bearing,
For longitude movement bearing,
For transverse movement bearing,
The design horizontal load of non-movement direction
is:
*5% of design vertical load: for areas where earthquake dynamic
peak acceleration: Ag=0.1g
*0% of design vertical load: for areas where earthquake dynamic
peak acceleration: 0.1g，less than the Ag of 0.*5g
*0% of design vertical load: for areas where earthquake dynamic
peak acceleration: 0.*5g, less than the Ag of
0.2g
For free movement bearing
For longitude movement bearing
For transverse movement bearing
The design horizontal load of movement direction is 5% of the
design vertical load.
The design rotation
angle is 0.*2rad
The
design displacement of a bearing: Design longitude
direction displacement for free movement bearing (DX) and
transverse movement bearing (ZX):
