Summary
New generation facility for impact testing. This project aims to develop a new generation, national-impact testing facility to study the impact response of civil and mechanical structures and components. This project expects to seek simultaneous, realistic impact scenarios with very high velocities, which were previously impossible. This will enhance the capability for innovative research on real-time behaviour of components/systems under high amplitude impacts to augment their protection throug ....New generation facility for impact testing. This project aims to develop a new generation, national-impact testing facility to study the impact response of civil and mechanical structures and components. This project expects to seek simultaneous, realistic impact scenarios with very high velocities, which were previously impossible. This will enhance the capability for innovative research on real-time behaviour of components/systems under high amplitude impacts to augment their protection through advanced materials. This project is essential for research on rational design philosophies and effective retrofitting of high-risk buildings, infrastructure and armoured vehicles. Benefits include the saving of lives and property through new knowledge from credible impact testing.Read moreRead less
Modelling rolling dynamic compaction. Modelling rolling dynamic compaction. This project aims to measure the influence and efficacy of rolling dynamic compaction (RDC)—a new ground improvement technology used worldwide—in soil types using RDC modules of different shapes and weights in an experimental testing facility. It will examine authentic 1:13 scale RDC models using sophisticated testing and instrumentation embedded in the soil, and use this data to develop a model based on artificial intel ....Modelling rolling dynamic compaction. Modelling rolling dynamic compaction. This project aims to measure the influence and efficacy of rolling dynamic compaction (RDC)—a new ground improvement technology used worldwide—in soil types using RDC modules of different shapes and weights in an experimental testing facility. It will examine authentic 1:13 scale RDC models using sophisticated testing and instrumentation embedded in the soil, and use this data to develop a model based on artificial intelligence techniques that reliably predicts ground improvement using RDC in different ground conditions. This research is expected to transform the Australian and global ground improvement sector, and save hundreds of millions of dollars in land development costs and infrastructure.Read moreRead less
Optimising the design, construction and cost-effectiveness of screw auger piles in fine-grained cohesive soils. The purpose of the project is to optimise the design, construction and effectiveness of screw auger piles used in fine-grained cohesive soils, through achieving an improved understanding of their behaviour and performance. The expected outcome is enhanced design and construction of such piles in these soils, and greater cost-effectiveness.
Control of cracking caused by early-age contraction of concrete. An extensive program of laboratory testing will be undertaken to quantify the extent of cracking in concrete walls and slabs due to early-age cooling and shrinkage of concrete. Analytical models for quantifying restraint in walls and slabs will be developed, as will methods for the prediction and control of crack widths and crack spacings.
The behaviour and design of composite columns coupling the benefits of high strength steel and high strength concrete for large scale infrastructure. This project will involve the development of a novel structural column system which will be more efficient, robust and require less maintenance than current systems. The outcomes will involve improved design methodologies which will enable large scale infrastructure to be enhanced and will involve the use of materials which improve sustainability.
Characterisation of shear and tensile fracture of ultra-high performance fibre reinforced concrete. This project aims to investigate the shear-tension interaction performance of ultra-high performance fibre reinforced concrete (UHPFRC). In January 2014, the draft Australian Standard for the design of concrete bridges was released; this is the first standard in Australia, and one of the first in the world, to include comprehensive design procedures for steel fibre reinforced concrete (SFRC).

This project aims to investigate the shear-tension interaction performance of ultra-high performance fibre reinforced concrete (UHPFRC). In January 2014, the draft Australian Standard for the design of concrete bridges was released; this is the first standard in Australia, and one of the first in the world, to include comprehensive design procedures for steel fibre reinforced concrete (SFRC). Rules allow conventional, strain softening SFRC, but exclude the use of strain hardening UHPFRC because of insufficient research on core aspects of the materials when conventionally reinforced. The study expects to provide vital data engineers and Standards bodies need to adopt UHPFRC.Read moreRead less

Summary
An Innovative and Advanced Systems Approach for Full Life-Cycle, Low-Emissions Composite and Hybrid Building Infrastructure. This project will develop a 'green' sustainable composite steel-concrete building frame system that reduces greenhouse gas emissions throughout the life-cycle of building construction, usage and deconstruction. It will eliminate the use of ordinary Portland cement, which is a major carbon dioxide producer, by using geopolymer concrete made from fly-ash, and will use econom ....An Innovative and Advanced Systems Approach for Full Life-Cycle, Low-Emissions Composite and Hybrid Building Infrastructure. This project will develop a 'green' sustainable composite steel-concrete building frame system that reduces greenhouse gas emissions throughout the life-cycle of building construction, usage and deconstruction. It will eliminate the use of ordinary Portland cement, which is a major carbon dioxide producer, by using geopolymer concrete made from fly-ash, and will use economic thin-walled, high-strength steel sections. Deconstructability is provided through bolted joints and by using tensioned bolts as shear connectors between the steel skeleton and concrete flooring. This project is underpinned by the extensive background of the candidate, and provides a very timely solution to a major contemporary engineering challenge facing Australia.Read moreRead less
Durability and debonding resistance of composite based strengthening techniques for deteriorated structures. Australia has many concrete structures exposed to aggressive environments that are deteriorating prior to their intended design life due to durability issues. Externally bonded fibre reinforced polymer composite applications are emerging as a method of structural rehabilitation. This project will provide safe and reliable strengthened structures.
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.
Performance of Soft Clay Consolidated by Biodegradable and Geosynthetic Vertical Drains under Vacuum Pressure for Transport Infrastructure. Along Australia's coast, the abundance of soft clay often hampers the design and construction of transport infrastructure including embankments. The use of vacuum pressure and prefabricated vertical drains (PVD) ensures rapid drainage and consolidation of the clay, thus increasing its shear strength and bearing capacity while reducing long term deformation. ....Performance of Soft Clay Consolidated by Biodegradable and Geosynthetic Vertical Drains under Vacuum Pressure for Transport Infrastructure. Along Australia's coast, the abundance of soft clay often hampers the design and construction of transport infrastructure including embankments. The use of vacuum pressure and prefabricated vertical drains (PVD) ensures rapid drainage and consolidation of the clay, thus increasing its shear strength and bearing capacity while reducing long term deformation. The main aim of this project is to achieve technological advancement in sustainable and cost effective PVD-vacuum systems by minimising the time to achieve the desired degree of consolidation, thereby controlling post construction settlement and lateral movement. Extensive laboratory and field studies supported by numerical modelling aim to result in new industry guides and standards.Read moreRead less
