DRAFT BRIDGE DESIGN SPECIFICATION (IN LIMIT STATE FORMAT), SECTION 8: BEARINGS AND EXPANSION JOINTS . BRIDGE ENGINEERING WORKSHOP; PROCEEDINGS; 14TH ARRB CONFERENCE, 28 AUGUST - 2 SEPTEMBER 1988, CANBERRA

Section 8 of the draft limit state code is essentially complete with only minor amendments and editorial changes anticipated before release of the final document. A commentary has been prepared. The new draft represents a major updating of the present code as well as conversion to a limit state format. The rules for elastomeric bearings have been completely revised. The new rules are generally based on the work of lindley, submissions from bearing manufacturers and a review of relevant German and English codes. Due to the material properties of elastomers and ptfe, and following overseas practice, elastomeric bearings and ss/ptfe sliding surfaces are only designed for serviceability limit state effects. The rules for fabricated bearings and expansion joints have been updated in accordance with modern practice. References to outmoded types of bearings have been deleted. Rules have not been provided for concrete hinges or ptfe lined spherical bearings. This new code continues the general naasra philosophy on bearings of: (a) for elastomeric bearings providing detailed information for the bearings and then load testing the bearings to check the manufacture; and (B) for fabricated bearings of specifying only on the most significant design parameters and leaving the design of the bearings to the manufacturer. The bearings are then proof tested to confirm the design and ensure that the friction of sliding surfaces is within design limits. For the covering record of the workshop, see IRRD no 814823.
