Victoria Bridge Design and Strengthening

The Victoria Bridge was opened in 1969 and is a key public and active transport link between Brisbane CBD and the southern suburbs. When it opened, it briefly held the world record for the longest span concrete box-girder bridge. This recorded webinar reviews the Bridge Upgrade Project covering the development of the design criteria and the detailed refurbishment and strengthening design, in the following two presentations:

Victoria Bridge: Development of a Design Criteria for the Strengthening & Refurbishment
Presenter: Eoin O’Donovan

This presentation provided a background and context to the completed Victoria Bridge strengthening and refurbishment project, including providing an overview of the original design and the initial load rating assessment. It also focusses on the need for departures from standards as well as the development of a concept for the strengthening design.

Victoria Bridge: Refurbishment and Strengthening Design
Presenters: Chris Ross and Nicolaj Pedersen

This presentation provides an overview of the various design strengthening methods utilised for the Victoria Bridge refurbishment. This includes the shear strengthening, the use of externally mounted post-tensioned tendons and the use of precast ultra high-performance concrete (UHPC) blisters. It also provides an overview of the bridge refurbishment along with describing how the design and detailing was carefully planned to ensure effectiveness while minimising the risk of damage during installation.
