Resilient Infrastructures
Oxford Economics forecasts a US$94 trillion investment in global infrastructure by 2040 to meet the demand for access to critical resources required by societies. The next-generation infrastructure in Singapore faces a series of new challenges, characterized by both climate-change driven environmental conditions and artificial hazards in an increasingly sophisticated modern infrastructure system. Multiple hazards may act simultaneously to pose safety threats to infrastructure systems, which were conventionally designed against a single extreme event. “Resilient infrastructure” here is therefore defined as infrastructure systems which are capable of retaining the basic operation and functionalities of the structures with sufficient structural capacity by absorbing multiple disruptions caused by artificial and environmental actions.
This research cluster aims to deliver multi-disciplinary and sustainable solutions to create smart and resilient infrastructural systems, which are not only robust in multi-hazard events, but also digitally enhanced to optimize the life-cycle cost in the framework of circular economy. To promote the understanding of resilience, knowledge-based analytics will be essential to profile the risks in infrastructure system failure and the dependence in the infrastructure network. The new resilient infrastructure relies fundamentally on the integration of sustainable high-strength materials in innovative structural solutions to deliver a durable system with reliable structural resistance. In the framework of the circular economy, infrastructure systems, which are adaptable to different purposes and functionalities in their design life, will significantly enhance the whole life value of the system and minimize the carbon footprint.
To equip our society with infrastructure adaptable to the future challenges described above, this research cluster thus embraces the following themes: design for multi-hazard robustness; risk of systemic failure of infrastructure and lifeline systems network; resilient infrastructures to mitigate climate change and seawater rise; sensor-interfaced digital twin solution for infrastructure resilience; mitigation measures in design of buildings against progressive collapse.
