Rapidwall is an Australian made new composite building product made from formulated gypsum plaster and glass-fibre. This is a high-tech building product that has huge potential to be developed into a dominant building material in the future. It is economic, labor effective, eco-friendly, structural sound and fire, thermal resistant and has many advantages over the existing building materials, such as concrete, steel and masonry. The lack of a technical design guidelines has fundamentally obstructed it from expanding its market share both in Australia and overseas. This proposal aims at developing a structural design manual for the new product.Read moreRead less
A New Generic Approach for Assessing Blast Effects on Reinforced Concrete Members. A framework allow for both flexural and shear response analysis using a new segmental approach is developed in this proposal. A blast test program is designed to validate the framework for reinforced concrete members. The validated framework is then used to derive normalised pressure impulse programs for reinforced members in unconfined and confined spaces. This project will provide design engineers guidelines for ....A New Generic Approach for Assessing Blast Effects on Reinforced Concrete Members.

A blast test program is designed to validate the framework for reinforced concrete members. The validated framework is then used to derive normalised pressure impulse programs for reinforced members in unconfined and confined spaces. This project will provide design engineers guidelines for reliably and quickly assessing the effect of different kinds of blast loads on different types and properties and geometries of reinforced concrete structural members, saving computation time and efforts while providing increased realism and accuracy.Read moreRead less
Combining transient micro-reflections and multi-sensor arrays for condition assessment of buried pipes. This project will develop an accurate and reliable approach for assessing the condition of pipelines. This new approach will reduce costs and save considerable amounts of water each year, as it will assist utilities in preventing major failures such as pipe bursts, and performing strategically targeted maintenance, replacement and rehabilitation.
Cost Effective Pipeline Condition Assessment Using Paired Pressure Sensor Arrays. Water distribution networks represent society's most important infrastructure asset. They are buried pipes and are often old and deteriorating. Cost-effective methods to assess their physical condition are urgently needed. This research will develop a novel and advanced approach to determine the interior condition of pipes quickly and effectively using small water hammer pulses or waves.

They are buried pipes and are often old and deteriorating. Cost-effective methods to assess their physical condition are urgently needed. This research will develop a novel and advanced approach to determine the interior condition of pipes quickly and effectively using small water hammer pulses or waves. Paired pressure sensor arrays will be used to measure reflections of the waves in pipes and these methods will enable finer resolution and identification of pipeline faults, such as wall thickness loss and leakage while at the same time allowing operational continuity. The outcome will be powerful tools to more cost effectively manage these crucial assets.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.

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

Much essential civil engineering infrastructure such as bridges, buildings, dams, pipelines and pavements was commissioned many decades ago, and sustaining the integrity of this infrastructure in developed nations as it ages is now considered to be a major challenge to the engineering and scientific community. Australia is not spared by the ramifications of its aging civil assets, and identification and rectification procedures that are often ad-hoc now represent a sizeable proportion of the GDP. This Research Network draws together the leading Australian research groups in engineering and applied mechanics in a coordinated program to address this most important cost to the community.Read moreRead less
