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.
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.

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

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
