Optimization of internal pressure for designing industrial buildings. The project seeks to understand the internal pressure in a building during windstorms, to improve safety and performance. The internal pressure in a building is dependent on its volume and flexibility and the sizes of openings in the building envelope, and is a critical loading parameter in building design.

The project seeks to understand the internal pressure in a building during windstorms, to improve safety and performance. The internal pressure in a building is dependent on its volume and flexibility and the sizes of openings in the building envelope, and is a critical loading parameter in building design. Windstorm damage investigations have shown that incorrect internal pressures are frequently used in building design, leading to damage. This project aims to study the internal pressures generated in buildings with a range of volumes and openings in the envelope. A combination of model-scale and full-scale tests and theoretical analysis are planned to determine critical parameters for highly turbulent air-flow though openings. Results will inform the revision of design data in codes and of guidelines for consistent, optimal design of buildings.Read moreRead less
Sustainable planting of trees in suburban environments on shrinkable clays. Sustainable planting of trees in suburban environments on shrinkable clays. This project aims to develop a rational and reliable model to reduce the risk of damage to structures and increase tree plantings in suburban environments.

Sustainable planting of trees in suburban environments on shrinkable clays. This project aims to develop a rational and reliable model to reduce the risk of damage to structures and increase tree plantings in suburban environments. Trees are vital to urban environmental sustainability, but local government, house-owners, engineers and the building industry are concerned about building damage and settlement from tree root drying. If tree water needs and patterns of moisture extraction were predictable, house footings could be designed reliably. This research will provide such understanding through field experiments on suburban sites with trees, investigating damaged structures and numerical modelling. An anticipated outcome of this research is to develop a rational and reliable model to reduce the risk of damage to structures and increase tree plantings in suburban environments. Guidelines for both footing designers and local government.Read moreRead less
Development of sophisticated structural design guidelines for the new building product known as Rapidwall. 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 material ....Development of sophisticated structural design guidelines for the new building product known as Rapidwall. 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
Experimental investigation and constitutive modelling of reactive soils. This project aims to develop the fundamental knowledge, a mechanical framework and practical engineering design tools needed to minimise the effects of reactive soils on infrastructure. Reactive soils undergo significant swelling and weakening upon wetting or intrusion by salt-rich groundwater and shrinkage upon drying. This can result in damage to buildings and infrastructure beyond a state of repair. This project will dev ....Experimental investigation and constitutive modelling of reactive soils. This project aims to develop the fundamental knowledge, a mechanical framework and practical engineering design tools needed to minimise the effects of reactive soils on infrastructure. Reactive soils undergo significant swelling and weakening upon wetting or intrusion by salt-rich groundwater and shrinkage upon drying. This can result in damage to buildings and infrastructure beyond a state of repair. This project will develop tools, models and theories to detect weaknesses in the design of infrastructure and its foundations built on problematic reactive soils, assess the impact and implement effective remedial measures to improve performance. The project is expected to increase efficiency through improved design and reduced damage, and save infrastructure owners, government and private, tens of millions of dollars each year.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.

This project aims to significantly reduce the number of pipe bursts in cities by detecting the leaks from developing cracks on water supply pipes just in time. New techniques will be developed for reliable and timely detection using the existing sensor network in the Adelaide CBD. Specialised monitoring stations will be developed with adaptive noise-cancellation algorithms to detect small leak signals in noisy city environments. Expected outcomes include an effective pipe burst early warning system and the implementation of an active burst prevention and targeted pipe replacement strategy. This should significantly reduce the burst rates and associated interruptions in Adelaide and save millions of dollars every year in pipe relay programs.Read moreRead less

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
