Design, specification, manufacture and testing of laminated elastomeric and pot bearings to AS 5100.4

This paper provides some notes for bridge designers on the specification of bearings to Part 4 of this Standard, "Bearings and Deck Joints" AS5100.4, and compares it with its forerunners, ABDC ('92/96 "Austroads Bridge Design Code, Part 4") and AS1523 "Elastomeric Bearings for Use in Structures", as well as other international codes. The authors discuss the need for a clear understanding between all team members involved in the design and manufacture of the bridge ( or building) and its critical components. The use of testing is discussed in detail, whether to "prove" designs of pot bearings, or for the quality control of LE bearings. Essential design parameters and their "permissible interaction" are discussed. The authors emphasise the information that must be transferred from the bridge designer to the bearing designer to permit an economical and adequate design of bearings. An example of a detailed Bearing Questionnaire is given, and some design rules additional to AS5100.4 are also suggested. (a) For the covering entry of this conference, please see ITRD abstract no.
