Elastomeric Bearings can be used with following possible arrangements
- Elastomeric Bearings provided on individual supports to transfer vertical loads and non-seismic lateral loads and to accommodate imposed deformations and translations. Seismic actions in this case are transferred to substructure by separate structural connections (either monolithic or through pin/guide bearings) of the deck to other supporting members (piers or abutments).
- On all or individual supports, with the same function as in a) above, combined with seismic links/seismic stoppers which are designed to resist seismic actions.
- On all supports to resist both seismic as well as non-seismic actions. Refer Annexure D of IRC: 83 Part II-2018 for design considerations when elastomeric bearings are used to resist seismic actions.
