Project Status:

This project will develop tools and techniques for implementing strategies to enhance resilience of road infrastructure to multi-hazards of floods, fire and climate change and earthquakes.

Road networks and critical road structures such as bridges, culverts and floodways have a vital role before, during and after extreme events to reduce the vulnerability of the community.

A major gap in the current research is the lack of assessment techniques and tools to reduce the vulnerability of road structures to enhance both community and structural resilience. This project is developing tools and techniques to enhance the resilience of road infrastructure to hazards such as floods, bushfires, earthquakes and climate change-related weather events.

The research commenced with an assessment of two case study regions in Victoria and Queensland, and the development of the methodology for vulnerability modelling of bridges and floodways. A field study was undertaken to examine the community impact due to the failure of roads during the 2011 and 2013 floods in the Lockyer Valley in Queensland.

A number of workshops were also held to identify case study data and refine the methodology for vulnerability modelling. Publications have included nine journal papers, 11 refereed conference papers and five other reports.

Major outcomes of the project have included development of the vulnerability modelling methodology for critical road structures exposed to extreme events and demonstration of the methodology using four case studies.

Enhancing resilience of critical road infrastructure: Bridges, culverts and flood-ways under natural hazards

Failure Mechanism of a Typical Girder Bridge in Australia due to Seismic Loads
18 Aug 2015

There is a significant need to perform adequate assessment of the vulnerability of bridges and bridge networks prior to future seismic events in Australia. This study aims to identify the failure mechanism of a typical girder bridge in Australia due to a seismic event and develop an earthquake management methodology based on a probabilistic based approach.

Capturing the Impact of the Failure of Critical Road Structures on the Community
18 Aug 2015

How does the performance of critical road structures such as bridges, culverts and floodways affect the community they serve; before, during and after the occurrence of a natural disaster?

It is important to assess the vulnerability of bridges in an extreme flood event as these critical infrastructures contribute to the resilience of the community during and in the recovery stage of the event.
