BGD Variable Stiffness Bearing Series

Variable stiffness bearings can coordinate the force distribution among piers of the same bridge span to better achieve collaborative seismic (vibration) resistance. They reduce design difficulties and save overall costs. Variable stiffness bearings have the characteristic of collaborative force distribution, allowing each bearing to share external forces to the greatest extent, preventing chain reactions due to individual bearings being damaged first. They can balance the stiffness differences among piers in the same bridge span, avoiding excessive load on "hard piers," especially suitable for mountainous bridges with significantly irregular high and low piers.

Variable stiffness bearings are particularly suitable for bridges with significant differences in high and low piers in mountainous areas, and are also suitable for highway and municipal bridges in areas with seismic fortification intensity of 7 degrees and above.

Other Products

Lasso shock-absorbing support

In normal use, the support moves within the range of designed displacement, the cable does not play a limiting role, and the cable damping support is the same as the conventional support.

LRB highway bridge lead core seismic isolation rubber bearing

The highway bridge lead core seismic isolation rubber bearing is a standard bridge component product developed in accordance with national and industry-related standards, while also referencing European standards. This product is available in two types: rectangular and circular, suitable for various highway and municipal bridges in seismic zones of 8 degrees and below.

GKPZ(Ⅱ) Seismic Rubber Bearing

The GKPZ type bowl rubber support consists of an upper seat plate, a lower seat plate, a middle steel plate, a pressure-bearing rubber plate, a copper sealing ring, a rubber sealing ring, a polytetrafluoroethylene plate, an SF-1B composite plate, a stainless steel plate, a damping rubber ring, and a shock-absorbing plate. The supports are divided into 31 specifications based on vertical load capacity, ranging from 0.8MN to 60MN. Its structure is consistent with that of ordinary bowl rubber supports, with the addition of damping rubber rings and shock-absorbing plates, providing good seismic and shock-absorbing performance. The horizontal load capacity of the unidirectional movable support and fixed support is 20% of the vertical load capacity.
