AS 5100.7:2017 PDF

Sets out a rating process for existing bridges to specify their safe capacity for carrying repeated traffic loads for their defined remaining service life.

This Standard was prepared by the Standards Australia Committee BD-090, Bridge Design, to supersede AS 5100.7—2004, Bridge design, Part 7: Rating of existing bridges. This Standard is also designated as Austroads publication AP-G51.7-17.

This Standard sets out requirements for the assessment of the geometry, condition, fatigue life, capacity and loading of existing road, rail, pedestrian or cyclist path bridges, culverts and associated structures. It is used to calculate the load rating factor of a bridge for a nominated rating vehicle.

The load and structural capacity requirements used in an assessment and load rating may differ from the original design load and structural capacity requirements because the bridge was not designed to this edition of the AS(AS/NZS) 5100 series. The nominated rating vehicles used for load rating may differ from the design load because of a change in use of the bridge.

Bridge assessment shall only be carried out after a Level 2 and/or Level 3 inspection has been undertaken to determine the current condition of the bridge. The method of assessing the ultimate capacity of a bridge for traffic loading shall be in accordance with this Standard.
