Project aims to further develop an engineering model for cost-effective innovative flood safety design/review for private dams in Southeastern Australia and integrate this with community impact assessment. Together, this is a "community partnerships" solution to a significant water policy vacuum on private dam safety and flood policy. Expected outcomes: improved risk transparency for dam owners and State Government, minimising costs of failures, ie. loss of life, damage to public and private infrastructure and environment; giving owners an affordable and effective design/review procedure to better manage their dams, providing data on community responses and water law reform proposals consonant with international best-practice.Read moreRead less

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

Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little ....Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little is known about the technology. This project will model the behaviour of rubber soil in order to introduce it as an environmentally sustainable, cost-effective and technically sound choice of geomaterial for both standard and non-standard geotechnical structures.Read moreRead less

Continuous non-invasive assessment of the physical condition of water distribution systems. Water distribution systems represent the single most important part of a society's infrastructure yet there are no comprehensive methods for detecting or assessing their physical condition. A suite of techniques (including those adapted from radar and sonar) for pro-active condition assessment will be developed in this research. The objective is to add significant intelligent and sophisticated numerical m ....Continuous non-invasive assessment of the physical condition of water distribution systems. Water distribution systems represent the single most important part of a society's infrastructure yet there are no comprehensive methods for detecting or assessing their physical condition. A suite of techniques (including those adapted from radar and sonar) for pro-active condition assessment will be developed in this research. The objective is to add significant intelligent and sophisticated numerical modelling capability to enable the non-invasive analysis of the transient pressure data, and to enable real-world application. This research will enable the continuous assessment of the physical condition of the entire water distribution system from an operations room resulting in significant savings.Read moreRead less
Influence of Spatial Variability on the Design and Performance of Pile Foundations. Currently, no model is available that incorporates the spatial variability of soil properties into the design and analysis of pile foundations. Furthermore, only basic rules-of-thumb are available to assist in determining the scope of appropriate site investigations for piles, and limited data are available for the LRFD of piles. The new and unique finite element model, site investigation guidelines and load re ....Influence of Spatial Variability on the Design and Performance of Pile Foundations. Currently, no model is available that incorporates the spatial variability of soil properties into the design and analysis of pile foundations. Furthermore, only basic rules-of-thumb are available to assist in determining the scope of appropriate site investigations for piles, and limited data are available for the LRFD of piles. The new and unique finite element model, site investigation guidelines and load resistance factors will reduce the over-design and uncertainty associated with pile design, which will lead to more reliable pile foundations and reduced construction cost overruns and delays. Conservatively, it is estimated that this research will result in savings in excess of $10 million per year, in Australia alone.Read moreRead less
Reducing the Risk of Foundation Failures by Improving the Effectiveness of Geotechnical Investigations. Inadequate geotechnical site investigation is the major factor in construction overruns and delays. In some instances failure may occur. Alternatively, such investigation may result in over-designed foundations. This research will examine these issues through sites, based on numerical simulations of variable soil conditions and investigations. Case studies will be used to verify the modelling. ....Reducing the Risk of Foundation Failures by Improving the Effectiveness of Geotechnical Investigations. Inadequate geotechnical site investigation is the major factor in construction overruns and delays. In some instances failure may occur. Alternatively, such investigation may result in over-designed foundations. This research will examine these issues through sites, based on numerical simulations of variable soil conditions and investigations. Case studies will be used to verify the modelling. A practical framework for planning and implementing geotechnical investigations, based on the variability of the soil profile will be developed. A key aspect of this framework is that, for the first time, site investigations will be linked to risk of foundation failure and cost of overdesign.Read moreRead less
Fibre reinforced polymer retrofitting of reinforced concrete flexural members. A cost-effective and durable technique for retrofitting reinforced concrete beams and slabs is to adhesively bond new advanced fibre reinforced polymer (FRP) composites to their surfaces.

A cost-effective and durable technique for retrofitting reinforced concrete beams and slabs is to adhesively bond new advanced fibre reinforced polymer (FRP) composites to their surfaces. The potential plating market in Australia for bridges is $350 million, however, the technique can also be applied to strengthening other structures such as buildings. Tests have shown that FRP plates or sheets can debond prematurely, which at present severely limits the application. The aim of this research project is to quantify the debonding mechanisms, strengths and ductilities of adhesively bonded FRP plated beams to provide design rules that can be used in practice.Read moreRead less
