AS 5100.4:2017 PDF Download

AS 5100.4:2017 establishes the fundamental guidelines for the design and performance of bearings and deck joints in bridge structures. The standard focuses on the specific purpose of these components, which is to allow for the relative movement of bridge elements such as decks, abutments, and piers. The standard addresses various types of bearings and deck joints, including elastomeric, pot, spherical, and mechanical varieties.

The AS 5100.4 standard outlines the crucial role that bearings and deck joints play in accommodating movements such as rotation and translation in bridge structures. These components ensure that the bridge can withstand the dynamic forces encountered during its lifespan, such as thermal expansion, seismic activity, and traffic-induced vibrations. The standard establishes minimum requirements for the design, performance, and installation of these components, emphasizing their vital contribution to the overall structural integrity and longevity of the bridge.

It is important to note that AS 5100.4:2017 specifically excludes concrete hinges from its scope. Concrete hinges are specialized components used to facilitate rotation and flexibility in certain bridge designs but are governed by different standards or practices. This exclusion ensures that this standard is focused on the requirements of elastomeric, pot, spherical, and mechanical bearings and deck joints. By setting out standardized guidelines, AS 5100.4:2017 aims to ensure that bridges are equipped with reliable and durable bearings and deck joints that can effectively accommodate movements and achieve safe operational conditions throughout their service life.
