AS 5100.8:2017 PDF Download

AS 5100.8:2017 is a standard that provides guidelines for the rehabilitation and strengthening of existing bridges. This standard outlines the minimum requirements and procedures for various purposes, including repairing or rehabilitating a structure to restore its original or intended level of service, extending the remaining service life of the structure, and strengthening the structure due to structural deterioration or to increase its capacity for various loading conditions such as live loads, collision loading, and seismic events.

The standard also covers the change in function of a structure, such as converting a road bridge into a pedestrian/cyclist bridge, as well as widening an existing structure. It encompasses various components of the bridge, including the superstructure, sub-structure, approach slabs, wing walls, and buried culverts.

However, it is important to note that rehabilitation or strengthening may not be possible for structures with certain limitations, such as substandard clearances, poor alignment, extensive substructure deterioration, deficient in situ strength, or non-redundant structural systems. Additionally, emergency response situations may require deviations from the standard requirements.
