Introduced nearly 60 years ago, laminated steel/elastomer bearing pads are now in service in tens of thousands of bridges and similar structures throughout the world.
There is good reason for this. They support vertical loads with minimal compression, allow expansion and contraction of the structure with minimal resistance, and provide for normal end rotation of bridge beams. In addition, they are easily installed and maintenance-free. All this is encompassed in a unit having the lowest cost per unit of supported load up to approx. 350 kips (1500 kN).
More sophisticated designs can be incorporated into an integrated structural system that channels horizontal loads to strong points and away from weaker ones. Ultimately, such systems are used to mitigate the severe loading conditions caused by earthquakes.
The Cosmec/Dynamic Rubber Team is pleased to offer laminated steel/elastomer bearings to suit any owner's or state specifications. With our extensive design experience, we can readily provide designs for specialty applications to meet unique design criteria or specific design requirements.
