Current design methods used for Controlled Modulus Column-supported embankments are outdated and uneconomical. This project aims to use innovative numerical and image processing techniques to develop new design methods that use 100% recyclable, environmentally friendly and highly durable EPS geofoam. Outcomes will advance the fundamental knowledge of bearing capacity increase of columns due to formation of smear zone and damages to nearby columns during installation. Numerical tools and design guidelines will be developed for engineers. The benefits include the design and construction of lighter, cheaper, safer and more stable embankments with significant cost and environmental gains from future infrastructure developments in Australia.Read moreRead less

Reusable Fire-Resistant Column Rehabilitation with Fibre Reinforced Polymer. The application of fibre reinforced polymer (FRP) composites in structural rehabilitation is sometimes challenged or opposed due to the limitation of its fire resistance. This project aims to solve the fire resistance problem of FRP in column jacketing work using innovative approaches.

The application of fibre reinforced polymer (FRP) composites in structural rehabilitation is sometimes challenged or opposed due to the limitation of its fire resistance. This project aims to solve the fire resistance problem of FRP in column jacketing work using innovative approaches. The proposed scheme will be developed by using advanced materials and mechanical fastening technology. It can ensure structural serviceability of FRP jackets during a fire. And after the fire, the proposed jacketing scheme is reusable by applying a new layer of epoxy. The project is expected to advance the theory and technologies in structural rehabilitation. It will also provide significant benefits to the construction industry via sustainable construction.Read moreRead less

Next generation Floating Structures with High-Performance Composites. Floating structures are facing severe deterioration problem due to steel corrosion. This project proposes to address the deterioration problem by developing prefabricated high-performance fibre-reinforced polymer (FRP)-ultra-high performance cementitious (UHPC) composite elements for future floating structures. FRP-UHPC composite elements have excellent strength-to-weight ratio and improved durability. Basic mechanical propert ....Next generation Floating Structures with High-Performance Composites. Floating structures are facing severe deterioration problem due to steel corrosion. This project proposes to address the deterioration problem by developing prefabricated high-performance fibre-reinforced polymer (FRP)-ultra-high performance cementitious (UHPC) composite elements for future floating structures. FRP-UHPC composite elements have excellent strength-to-weight ratio and improved durability. Basic mechanical properties and durability of FRP-UHPC composites will be investigated. Also, reliable connection device for FRP-UHPC structural units will be proposed and verified. The project is expected to provide durable floating structures with low maintenance cost, leading to a revolution of the current floating structures.Read moreRead less

Fibre Reinforced Polymer (FRP)-Confined Concrete-Encased Steel Composite Columns.

The infrastructure in Australia and beyond has long suffered from deterioration due to corrosion of steel reinforcement/sections. This project will address this problem by investigating a new form of hybrid columns, namely fibre reinforced polymer confined concrete-encased steel composite columns. The idea of combining a fibre reinforced polymer-confined concrete and a steel section not only makes the column a durable and ductile alternative to steel/concrete columns, but also makes them an efficient method for retrofitting or strengthening deteriorated steel columns. This project will study the structural behaviour of fibre reinforced polymer confined concrete-encased steel composite columns, and develop design methods to pave the way towards their wide practical applications.

Hybrid multiple-tube concrete columns incorporating composite materials. The project aims to investigate the behaviour of and design hybrid multiple-tube concrete columns, a form of column. These columns allow the use of small circular high-strength steel tubes, readily available in the market, to suit the specific needs of construction projects of various scales. In the column, a durable outer tube made of fibre-reinforced polymer (FRP) composites protects steel tubes, and their high yield stre ....Hybrid multiple-tube concrete columns incorporating composite materials. The project aims to investigate the behaviour of and design hybrid multiple-tube concrete columns, a form of column. These columns allow the use of small circular high-strength steel tubes, readily available in the market, to suit the specific needs of construction projects of various scales. In the column, a durable outer tube made of fibre-reinforced polymer (FRP) composites protects steel tubes, and their high yield stress can be fully exploited through section configuration. The new column is expected to enable wider, safer and more economical use of FRP and high-strength steel, and meet demands for resilient civil infrastructure.Read moreRead less
Short- and long-term corrosion of steels in highly calcareous seawaters . This project aims to quantify the development of the long-term (25-100 year) protective effect of calcareous deposits on the marine corrosion of mild steels. This is significant because such steels used extensively in major and very expensive coastal and offshore infrastructure. The project outcomes will improve scientific understanding, including the role of microbiological activity. It will develop and calibrate corrosio ....Short- and long-term corrosion of steels in highly calcareous seawaters . This project aims to quantify the development of the long-term (25-100 year) protective effect of calcareous deposits on the marine corrosion of mild steels. This is significant because such steels used extensively in major and very expensive coastal and offshore infrastructure. The project outcomes will improve scientific understanding, including the role of microbiological activity. It will develop and calibrate corrosion prediction models using classical and recently available 100 year data from Europe, the Pacific, Australia and also new project-specific experimental data. These models are expected to be of benefit for Australian engineering consultants in maintain their internationally competitive edge in offshore engineering.Read moreRead less
