Resilient Infrastructure research at UNSW Canberra focuses on the design, operation, maintenance, and protection of infrastructure to mitigate disaster risks that arise from a variety of hazards. Our team of experts have developed significant research capability in vulnerability modelling and assessing the effects of man-made, cyberspace, and natural hazards on buildings and critical infrastructure. We aim to ensure infrastructure systems can withstand, adapt to, and recover quickly from anticipated or unexpected shocks and stresses - now and in the future.
Natural & Man-made Hazards
Natural disasters, extreme weather events, the changing climate, and man-made hazards have destructive and devastating consequences on human society and the natural environment. This includes earthquakes, tsunami, flooding, fire, and war. Critical infrastructure often sustains a high amount of damage as a result of these events.
Our research supports adaptation to ensure critical building and infrastructure projects can withstand significant and unexpected changes in the social and physical environment within which they are designed, built, and operated, beyond the normal day-to-day demands of their strengths and capacities. Our research covers the:
- development of new resilient structures using advanced protective systems and new materials such as high strength steel, polymers, ceramics, auxetics, and fabrics.
- planning, design, and management of sustainable and resilient transportation systems to guarantee a timely response to natural or man-made disruptions.
- development of efficient and effective solutions to technological challenges against natural and man-made threats such as gas explosions, improvised explosive devices (IEDs), combined impact and base loading, vehicle collisions, and hail damage.
- development of advanced simulation, validated numerical platforms, and finite element analysis (FEA) codes and the provision of a wide range of consultations and training opportunities to relevant stakeholders.
- provision of risk management and modelling, and innovative protection solutions to improve the resilience of geotechnical structures such as bridges, tunnels, or dams.
- design and operation of flexible off-grid renewable energy supply systems.
Services such as water, gas, electricity, and transportation systems are enhanced with the digitisation of critical infrastructure and widespread adoption of network and remote monitoring and control technologies. However, this evolution has also extended the attack surface for cybersecurity incidents to impact critical operations.
Given the increasing number of cyber-attacks globally, our research explores the resilience of critical infrastructure systems with a focus on:
- intrusion detection and prevention for supervisory control and data acquisition (SCADA), industrial internet of things (IoT), and cyber-physical systems. These systems are part of a network and use computer-based algorithms to remotely monitor and control functions of pipeline operations.
- the use of artificial intelligence to analyse abnormal data. This data can be used to pinpoint and address cyber vulnerabilities quickly and protect computer systems, networks, and individuals from potential threats.
