Bearing Pads

Bearing Pads are often used to enhance the performance of prestressed/precast concrete structures. The purpose in design for using bearing pads is to uniformly distribute loads over the bearing area, absorb impact and to permit limited horizontal and rotational movements between two structural members, while providing stress relief in these areas. Additional characteristics are their ability to expand and contract, absorb vibration and shock to reduce the destructive action between moving and stationary prestressed/precast members.
