Bridge Bearing Pads: POT_BEARING
Elastomeric and other bridge bearing pad design properties per AASHTO LRFD Section 14.7 — plain elastomeric, steel-reinforced, PTFE sliding, disc, and pot bearings with shear modulus, compressive stress limits, and creep factors
| bearing type | durometer | compressive stress limit ksi (ksi) | creep factor (dimensionless) | design method | max total compressive stress ksi (ksi) | notes | temp range F |
|---|---|---|---|---|---|---|---|
| POT_BEARING | N/A | 3.5 | 0.1 | Method B | 3.5 | Confined elastomer in pot; unlimited rotation; compressive limit 3.5 ksi; used for long bridges with large movements | −30 to 130 |
