Earthquake protection of masonry buildings using fibre reinforced polymer strengthening. The importance of this research is highlighted, both nationally and internationally, by the work of the insurance industry which reported that the economic risk posed by a moderate earthquake in any of the capital cities in Australia is of the order of billions of dollars (Blong, 1993). For example, a 'design magnitude' earthquake in Sydney is predicted to cause, just in domestic construction, over $10 bill ....Earthquake protection of masonry buildings using fibre reinforced polymer strengthening. The importance of this research is highlighted, both nationally and internationally, by the work of the insurance industry which reported that the economic risk posed by a moderate earthquake in any of the capital cities in Australia is of the order of billions of dollars (Blong, 1993). For example, a 'design magnitude' earthquake in Sydney is predicted to cause, just in domestic construction, over $10 billion damage and more than 5000 deaths. Most of this damage would be associated with unreinforced masonry construction such as low-rise apartment buildings. The damage bill for the entire built environment (with business interruption costs) could easily be an order of magnitude greater.Read moreRead less
Mitigating Vehicular Crashes into Masonry Buildings . Around 2000 vehicles crash annually into school, home and shop buildings located at close proximity to heavily trafficked roads in Australia and cause significant distress to occupants of building and vehicle. The impacted walls mostly of masonry, suffer severe damage often with vehicle intrusion into the building. Despite this, the intrusion mechanism is not understood and no effective mitigation strategies exist at present. This project wi ....Mitigating Vehicular Crashes into Masonry Buildings . Around 2000 vehicles crash annually into school, home and shop buildings located at close proximity to heavily trafficked roads in Australia and cause significant distress to occupants of building and vehicle. The impacted walls mostly of masonry, suffer severe damage often with vehicle intrusion into the building. Despite this, the intrusion mechanism is not understood and no effective mitigation strategies exist at present. This project will uncover the mechanics of vehicle intrusions through masonry walls and develop novel mitigation strategies using high energy absorbing auxetic composite render and innovative vibration isolation at wall edges. These innovations will lead to new theories that can save lives in the building and vehicle.Read moreRead less

It is expected that this project will develop novel design rules for ultra-high performance geopolymer concrete thin-walled structures based on experimental testing, numerical modelling, validation, and simulation. This project is expected to increase the durability of coastal infrastructures and significantly reduce the loss of their capacities due to corrosion-induced damage. The development of ultra-high performance geopolymer concrete thin-walled structures is a significant engineering discovery, which is in line with the Australian government 2030 vision for sustainable development.Read moreRead less
A new strategy for design flood estimation in a nonstationary climate. Evidence suggests that global warming will result in an increase in the frequency and/or magnitude of heavy rainfall, leading to flooding with potentially devastating consequences. This study provides a renewed focus on design flood estimation that takes into account a changing climate where assumptions of stationarity are no longer tenable.
A Stochastic Spatial Rainfall Model for Engineering Risk Assessment. Current Australian hydrologic design practice is moving towards use of continuous simulation to more accurately evaluate the performance of the water-related infrastructure for managing floods and droughts. A major impediment is the inability to simulate the temporal and spatial variability of rainfall. This project aims to develop a stochastic rainfall model that will simulate long records of representative six-minute duration ....A Stochastic Spatial Rainfall Model for Engineering Risk Assessment. Current Australian hydrologic design practice is moving towards use of continuous simulation to more accurately evaluate the performance of the water-related infrastructure for managing floods and droughts. A major impediment is the inability to simulate the temporal and spatial variability of rainfall. This project aims to develop a stochastic rainfall model that will simulate long records of representative six-minute duration rainfall throughout the target region. The proposal introduces a three-level hierarchical model of space-time rainfall building on experience of a point rainfall model developed in previous ARC research. Practical issues dealing with data quality and validation will also be addressed.Read moreRead less

Water distribution systems represent the single most important part of a society's infrastructure yet there are no comprehensive methods for detecting or assessing their physical condition. A suite of techniques (including those adapted from radar and sonar) for pro-active condition assessment will be developed in this research. The objective is to add significant intelligent and sophisticated numerical modelling capability to enable the non-invasive analysis of the transient pressure data, and to enable real-world application. This research will enable the continuous assessment of the physical condition of the entire water distribution system from an operations room resulting in significant savings.Read moreRead less
Reducing the Risk of Foundation Failures by Improving the Effectiveness of Geotechnical Investigations. Inadequate geotechnical site investigation is the major factor in construction overruns and delays. In some instances failure may occur. Alternatively, such investigation may result in over-designed foundations. This research will examine these issues through sites, based on numerical simulations of variable soil conditions and investigations. Case studies will be used to verify the modelling. ....Reducing the Risk of Foundation Failures by Improving the Effectiveness of Geotechnical Investigations. Inadequate geotechnical site investigation is the major factor in construction overruns and delays. In some instances failure may occur. Alternatively, such investigation may result in over-designed foundations. This research will examine these issues through sites, based on numerical simulations of variable soil conditions and investigations. Case studies will be used to verify the modelling. A practical framework for planning and implementing geotechnical investigations, based on the variability of the soil profile will be developed. A key aspect of this framework is that, for the first time, site investigations will be linked to risk of foundation failure and cost of overdesign.Read moreRead less
Impact of rolling dynamic compaction. The project will lead to improved understanding and greater use of rolling dynamic compaction (RDC). RDC is a relatively new compaction technique that can be used to improve soft and derelict ground prior to the construction of roads, railways, subdivisions and structures. This project will also lead to greatly reduced ground improvement costs.
A spatial extremes framework for predicting subdaily rainfall intensity. Climate change is causing extreme rainfall intensity to increase globally. The greatest increases occur for short-duration storms lasting up to several hours, bringing a heightened risk of flash-floods that are often extremely hazardous due to their rapid onset. The project aims to develop a new spatial extreme value framework to predict extreme rainfall patterns, using insights on future changes to rainfall triggering mech ....A spatial extremes framework for predicting subdaily rainfall intensity. Climate change is causing extreme rainfall intensity to increase globally. The greatest increases occur for short-duration storms lasting up to several hours, bringing a heightened risk of flash-floods that are often extremely hazardous due to their rapid onset. The project aims to develop a new spatial extreme value framework to predict extreme rainfall patterns, using insights on future changes to rainfall triggering mechanisms (e.g. convective, frontal or orographic). The research aims to provide projections in the form of intensity-frequency-duration curves, areal reduction factors and antecedent rainfall depths. Engineers are expected to use this information to design infrastructure and urban planning policies to adapt to future flood risk.Read moreRead less
