Bridge Bearing Pads: DISC_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 |
|---|---|---|---|---|---|---|---|
| DISC_BEARING | N/A | 3.5 | 0.2 | Method B | 3.5 | Polyether urethane disc; resists rotation; compressive stress limit 3.5 ksi; used for high rotation and translation | −10 to 120 |
