This project aims to develop next generation construction of multi-hazard resilient structures for the safety and wellbeing of the public, society and economy, as well as structural health monitoring techniques for effective engineering asset management. Sustainable infrastructure development involves the use of green materials to reduce greenhouse gas emission, and new technologies to reduce construction and life-cycle maintenance cost. The project will use new green materials and techniques to prefabricate structural components which can be easily assembled and dismantled to meet the requirement for adaptation to technology advancement, urban planning and climate change. The project will advance the construction practice for sustainable infrastructure development.Read moreRead less

Conventional concrete is made using fresh water and river sand. This project aims to develop a novel hybrid construction system using seawater, sea sand and industrial waste, together with fibre reinforced polymer (FRP) and stainless steel (SS), for use in civil engineering infrastructure in marine environments. To date there has been little work to understand the degradation kinetics and mechanisms of FRP and SS in such complicated corrosive environments. The project plans to provide a design methodology to ensure confidence in the safety of critical infrastructure such as bridges, highways, dams, airports, offshore piles and artificial islands. The proposed system would save fresh water and reduce damage to river ecosystems, carbon dioxide emissions and construction costs.Read moreRead less

This project aims to develop a cost-effective technique to mitigate the safety risk posed by the many unreinforced brick masonry parapets and walls which are vulnerable to seismic shock. Every Australian city has many streets lined with older unreinforced brick masonry buildings (now cafes, pubs, boutique shops) which feature parapets. The project will provide benefits to society by reducing the potential for parapet collapse and therefore reduce the total number of fatalities in an earthquake. Building owners and engineers will be benefit from the design guidance provided by this project, which will lead to a suite of fully-tested and low-cost retrofit techniques.Read moreRead less

This project will develop new and innovative ways of constructing steel structures using the rising factory concept. The rising factory is a 10 storey enclosure where the final high-rise building is safely constructed within a watertight envelope which rises as the building progresses. The project will perform the necessary research to make possible high-rise steel structural systems consisting of hot-rolled (heavy gauge) and cold-formed (light gauge) steel structural members and connections which can be used in the rising factory. The main benefits of the rising factory are the waterproof construction environment and the substantially increased safety as a result of no external cranes.
