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.

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


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

Capturing the Impact of the Failure of Critical Road Structures on the Community


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.

The research is focused on the assessment of the vulnerability of a concrete u-slab bridge as a bridge type widely used in australia and simulation of the structure exposed to the different flood intensities and its consequent log impact.

Focus of this research is to assess the performance of existing composite steel girder bridges to most rational bushfire (bf) and hydrocarbon (hc) fire events.

There is a significant need to perform adequate assessment of the vulnerability of bridges and bridge networks prior to future flood events in Australia.

Key Topics:
Performance analysis of composite steel girder bridge structural elements subjected to bushfires


The focus if this research is to assess the performance of existing composite steel girder bridges to most bushfire (bf) fire events. Effect of a bushfire was first evaluated based on available experimentally measured bushfire time temperature data. Then the bushfire itself and its effect were calculated with physics based fire dynamic analysis. The aim of this research is to identify a range of critical fuel geometries and fields characteristics which could result in potential damage to a structure.

Measuring social, environmental and economic consequences of road structure failure due to natural disasters


Road infrastructure plays an important role after a disaster and is a vital factor influencing recovery and reconstruction activities. This project aims to develop a framework to measure social, environmental and economic consequences of disaster related road failure, which will help to understand the wider impacts of road failure in a post-disaster context.

Collapse risk assessment of strengthened concrete bridge pier under flood loads


A  fluid structure interaction using particle finite element method for the full scale reinforced concrete bridge is built to simulate the deformations of bridge piers under flood loads. The critical pier will then be tested using 6-degree of freedom system, from which the finite element model of bridge model will be calibrated. Fragillity assessment of bridge pier before and after strengthening will be performed to study the effectiveness of strengthening for enhancing the resilience of bridges under flood loads.

Water flow pressure changes on circular and square bridge piers under increasing velocity floods


Resistance to flood is a critical parameter affecting the design of the bridges. Typical design process would convert the flood loading in to a static force which can not reflect the full effect of flood loading on piers of different shape. Therefore it is important to investigate the effect of flood loading on piers of different shape. This work simulates the flooding effect on the piers using a finite volume method in ANSYS Fluent. The pier is modelled as a column with a square cross section or a circular cross section.
