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.
Adaptive Base Isolation using Innovative Magnetorheological Elastomers. Base isolation is of great importance for the safety of infrastructure, such as hospitals, bridges and nuclear power plants. Utilisation of a traditional passive base isolator makes the base isolation system vulnerable and susceptible to unexpected/extreme dynamic loadings, such as earthquakes. This project aims to address this critical issue through the development of a novel adaptive seismic isolator working with an innova ....Adaptive Base Isolation using Innovative Magnetorheological Elastomers. Base isolation is of great importance for the safety of infrastructure, such as hospitals, bridges and nuclear power plants. Utilisation of a traditional passive base isolator makes the base isolation system vulnerable and susceptible to unexpected/extreme dynamic loadings, such as earthquakes. This project aims to address this critical issue through the development of a novel adaptive seismic isolator working with an innovative stiffness softening magnetorheological elastomer (MRE). This research represents a fundamental step towards the understanding of MRE behaviour and is expected to be the breakthrough for the development of a future smart base isolation system.Read moreRead less

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
Rotation Capacity of Joints in SFRC Moment Resisting Beams and Frames. 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 design procedures for steel fibre reinforced concrete (SFRC) in a comprehensive way. While rules have been introduced for flexure and shear, strict limitations are placed on application where large plastic rotations are expected. This study invest ....Rotation Capacity of Joints in SFRC Moment Resisting Beams and Frames. 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 design procedures for steel fibre reinforced concrete (SFRC) in a comprehensive way. While rules have been introduced for flexure and shear, strict limitations are placed on application where large plastic rotations are expected. This study investigates the moment-rotation performance of SFRC beam-column connections containing economical fibre dosages. The study is expected to provide data on the post-ultimate behaviour and robustness of SFRC moment hinges and determine moment-rotation relations for adoption by engineers and Standards bodies.Read moreRead less
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

The aim of this project is to develop the fundamental understanding needed to design and construct high-strength concrete columns with high-strength steel reinforcement, with the intended outcome of providing design rules for adoption by engineers and Standards bodies. With significant innovations in Australian steel bar technology, strengths grades of 750 megapascals, and higher, are becoming available. These high-strength steels can be used in reinforced concrete building construction and would increase the competitiveness of Australia's manufacturing industry and enable the export of high-value-added technologies. Significant efficiencies in construction costs and in carbon emissions are possible.Read moreRead less
The behaviour and design of innovative connections to promote the reduction and reuse of structural steel in steel-concrete composite buildings. This proposal will study the behaviour of innovative connections to promote the reduction and reuse of structural steel in steel-concrete framed buildings. Steel is one of the most recycled materials on earth, however it is the reduction and reuse rather than recycling which can provide significant benefits to building construction.

This proposal will study the behaviour of innovative connections to promote the reduction and reuse of structural steel in steel-concrete framed buildings. Steel is one of the most recycled materials on earth, however it is the reduction and reuse rather than recycling which can provide significant benefits to building construction. Economic and technical issues have impeded the widespread application of the reuse of steel. These technical impediments can be addressed through the development of connections that promote dismantling of structures at the end of a building's life. This project will address this issue by developing innovative structural connections through experimental and analytical studies and design code provisions.Read moreRead less
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.
Durability of carbon fibre reinforced polymer (CFRP) strengthened steel structures against environment-assisted degradation. This research project will challenge conventional methods of repairing or strengthening steel structures by using carbon fibre reinforced polymer with advanced epoxy. The outcome of this research is to remove the biggest barrier to the full utilization of such advanced material in civil, offshore and mining industry.
Performance of safety critical anchors in early age concrete with SCM. This project aims to examine the performance of anchors in a range of cements, to contribute to new safety and building guidelines. Demands for faster construction cycles and increased productivity require anchors for lifting and joining concrete elements to be installed and loaded in early age concrete. Yet, best practice for evaluation of anchors is based on mature concrete. There is also increasing use of supplementary cem ....Performance of safety critical anchors in early age concrete with SCM. This project aims to examine the performance of anchors in a range of cements, to contribute to new safety and building guidelines. Demands for faster construction cycles and increased productivity require anchors for lifting and joining concrete elements to be installed and loaded in early age concrete. Yet, best practice for evaluation of anchors is based on mature concrete. There is also increasing use of supplementary cementitious materials with unknown effects on anchors. This project aims to address this construction industry challenge. The project plans to study experimentally and analytically the effect of early age creep on anchor installation and the factors affecting the slip behaviour and ultimate performance of cast-in and post-installed mechanical anchors in concretes. It is intended that these studies will then inform new design guidelines.Read moreRead less
