Plain elastomeric bearing pads (PEP) rely upon friction at the contact surfaces to resist bulging. Local slip resulting from friction loss leads to increased strain, thus limiting the load carrying capacity of the bearing.
Redwood Plastics is the exclusive manufacturer of Redco™ Dynamex™ Engineered Elastomeric Bearings for Bridges and Structures. Redco™ Dynamex™ products conform to CAN/CSA, AASHTO, AREMA and OPSS standards and are available in a wide range of configurations.
Neoprene Bearing Pads are used extensively in bridge structures. Natural rubber (with the appropriate formulation) provides good resistance to traction, excellent failure strain and performs well with dynamic loads and in the cold, although it does tend to crystallize.
Laminated bearings consist of elastomer material vulcanized to layers of unexposed steel shims. These bearing pads allow for more rotation and movement capabilities than plain bearing pads.
1 cze 2023 · An elastomeric bearing pad plays a crucial role in bridge safety, dependability, and longevity. Read how simulation helps.
Elastomeric bearings allow transfer of vertical loads, horizontal movement, and structural rotation. They are valued for their durability, reliability, low maintenance requirements, and low cost. Because elastomeric bearing pads are crucial for safe and cost-effective concrete bridge design, we posed questions about them to the experts.
