AS 5100 Bridge Design Concrete Updates

This recorded webinar provides a background to the recent amendments to Australian Standard AS 5100 Bridge Design – Part 5, Concrete. The amendments are significant and reflect the developments in concrete bridge design and assessment since the Standard was issued in 2017.   Durability provisions have also been revised.  A focus has been to achieve alignment with the Concrete Structures Standard AS 3600: 2018, where appropriate. We have invited two eminent members of the Bridge Design community and members of the BD090-05 subcommittee, John Hilton and Wayne Roberts, to present a review of the changes, the background, and rationale for incorporation of these amendments into the Standard. This module is not only applicable to bridge designers and specifiers, but to all concrete design, specification, construction, and materials practitioners.
Designing concrete bridges to the new strength and serviceability provisions of the recent AS 5100.5 Amendment
Presenter: John Hilton
John’s presentation will include the new provisions for concrete and reinforcement design under fatigue loading, implications of new requirements for reinforcement detailing and MCFT shear design, steel relaxation under elevated temperatures, introduction and benefits of higher strength steel reinforcement which is now available, new requirements for punching shear and the importance of reinforcement anchorage.  Some comparison will be made with the provisions of AS 3600 and upcoming future introduction of Ultra High-Performance Concrete for bridges.  The implications of sustainability; embodied carbon, service life and resilience will also be discussed.
A detailed look at the updated durability section of AS5100.5, along with some insights on concrete material properties and some construction related issues
Presenter: Wayne Roberts
Wayne’s presentation will provide a detailed insight into the updated durability design provisions in Section 4 of AS5100.5 stepping through some of the changes and the reasons and background for these changes that influence both the durability design and some of the construction aspects of concrete bridges.  A review of some of the concrete material property updates, along with some insights into the inter-relationships between materials, design and construction will also be discussed.
