Bridge Bearing Design to AASHTO LRFD
The following design was developed based upon the above referenced AASHTO LRFD code. The program is applicable to the design of elastomeric pads and steel reinforced elastomeric bearings, both rectangular and circular in shape. For steel reinforced elastomeric bearings and fiber reinforced pads, the fiberglass reinforcement comprising Hs shall be assumed to consist of double fiberglass layer separated by 0.125in. Bonding layer per article 14.7.6.3.1. Compression deflections and anchorage requirements for bearings are to be verified by thee user in accordance with provisions outlined in article 14.7.6.3.3 and 14.7.6.4 respectively.
