The Influence of Cement Type, Age and Curing Conditions on the Flexural Capacity of Masonry Walls. The use of cements containing waste products such as fly ash and blast surface slag has increased markedly. This has desirable environmental and economic consequences, but the influence of these cements on the bond strength of masonry constructed from mortars containing these cements is unknown and in urgent need of clarification. This investigation studies this effect as well as the influence of ....The Influence of Cement Type, Age and Curing Conditions on the Flexural Capacity of Masonry Walls. The use of cements containing waste products such as fly ash and blast surface slag has increased markedly. This has desirable environmental and economic consequences, but the influence of these cements on the bond strength of masonry constructed from mortars containing these cements is unknown and in urgent need of clarification. This investigation studies this effect as well as the influence of age and curing conditions on masonry flexural strength at both a fundamental and applied level, thus allowing the impact of the use of mortars containing these cements on actual building performance to be assessed.Read moreRead less
Mechanics of dynamic loading and rapid penetration of soils. The project will produce improved understanding and new numerical tools that will permit cost effective simulation and modelling of rapid penetration of objects into the ground, and of the compaction processes used on the majority of construction sites. The free fall penetrometer will be developed to enable soil strength to be determined at remote sites, e.g. ocean seabed, jungles, swamps. The project will also assist in the selection ....Mechanics of dynamic loading and rapid penetration of soils.

Cracking of Embankment Dams Under Normal Operating, and Flood Conditions, and the Implications for Internal Erosion and Piping Failure. Internal erosion and piping causes half of embankment dam failures and accidents. Historically about two percent of dams have been affected. The most common cause of initiation of erosion is in cracks or by hydraulic fracture in low stress zones. This project will develop methods for predicting the opening width and depth of desiccation and stress induced cra ....Cracking of Embankment Dams Under Normal Operating, and Flood Conditions, and the Implications for Internal Erosion and Piping Failure. Internal erosion and piping causes half of embankment dam failures and accidents. Historically about two percent of dams have been affected. The most common cause of initiation of erosion is in cracks or by hydraulic fracture in low stress zones. This project will develop methods for predicting the opening width and depth of desiccation and stress induced cracking in the dam crest, and for assessing whether the cracks will close before erosion begins as the reservoir water rises, or whether erosion will self limit or continue.Read moreRead less
Cost-effective integrated engineering and "community partnerships" solution to a latent water policy issue: private dam management and flood safety. 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.

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
Turbulence and energy dissipation in stepped spillways and urban drainage systems. The economical sustainability of Australia's water resources relies upon an efficient use of its structures. Present water resources are diminishing because of poor engineering design. This issue is critical in both rural and urban Australia.

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.

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
Strength of two-way steel fibre reinforced composite flooring systems. The construction industry in Australia is introducing efficient and economical long-span profiled steel sheeting for composite flooring systems, and Steel Fibre Reinforced Concrete (SFRC) applications are becoming widespread.

The construction industry in Australia is introducing efficient and economical long-span profiled steel sheeting for composite flooring systems, and Steel Fibre Reinforced Concrete (SFRC) applications are becoming widespread. Australia is a recognised world leader in the research of both composite structures and SFRC. Using SFRC in composite decks to eliminate conventional reinforcement is very efficient and cost-effective, but surprisingly little relevant research aimed at the Australian industry has been reported. Comprehensive design guidance is much needed to advance this technology. This project will give designers confidence and expertise to advance these technologies, while maintaining Australian research and practice in composite structures at the forefront.Read moreRead less
Time-Dependent Response and Deformations of Composite Beams with Innovative Deep Trapezoidal Decks. The construction industry in Australia is introducing efficient and economical long-span trapezoidal profiled steel sheeting for composite flooring systems. Australia is a world leader in the research of composite structures.

The construction industry in Australia is introducing efficient and economical long-span trapezoidal profiled steel sheeting for composite flooring systems. Australia is a world leader in the research of composite structures. Composite beams undergo deformations because the concrete creeps and shrinks, and because the slab slips relative to the steel joist. Surprisingly little research has addressed these issues collectively; they are of paramount significance with trapezoidal decks and research is much-needed. This research will investigate the interaction of creep, shrinkage and partial interaction in these composite beams, producing valuable design guidance to keep Australian research and practice at the forefront internationally.Read moreRead less
