Interactions between volumetric units in modular buildings. This project aims to develop an in-depth understanding of the interactions between volumetric units in modular buildings to develop integration strategies for the interconnection of modules.

This project aims to develop an in-depth understanding of the interactions between volumetric units in modular buildings to develop integration strategies for the interconnection of modules. The uptake of modular construction has been hindered by the technical complexities of the design process for manufacture and assembly, in particular the flexible connection of services. By addressing significant gaps in the guidance on the design of modular interconnections and their integration strategies, this project expects to enhance the industry’s capacity to adopt safe, economical and standardised designs of modular systems. This project should significantly reduce the risk in decision making in modular construction, and transformation to advanced building manufacturing technologies in Australia and beyond.Read moreRead less
Seismic attenuation of structures through use of magnetorheological dampers. This project aims to improve understanding of the attenuating characteristics of the co-flowing of magnetised solid particles and fluid in a conduit subject to seismic waves generated by rapid ground movement. The distribution of magnetised solid particles in fluid plays an important role in the design of large-scale magnetorhelogical dampers for seismic conditions. These dampers promote the protection of historical str ....Seismic attenuation of structures through use of magnetorheological dampers. This project aims to improve understanding of the attenuating characteristics of the co-flowing of magnetised solid particles and fluid in a conduit subject to seismic waves generated by rapid ground movement. The distribution of magnetised solid particles in fluid plays an important role in the design of large-scale magnetorhelogical dampers for seismic conditions. These dampers promote the protection of historical structures and eliminate costly rebuilding of architectural structures. The project plans to perform experimental and numerical investigations to develop robust and accurate predictive models to improve understanding of the seismic attenuation of next-generation magnetorhelogical dampers, prevalent in semi-active control devices, and of the ability of such devices to suppress elevated structural vibrations.Read moreRead less
Engineering floating liquid marbles for three-dimensional cell cultures. This project aims to understand the physics of three-dimensional cell cultures in a liquid marble floating on a liquid free surface. New methodology developed can produce these cell cultures without using matrices or scaffolds and with run-times well beyond existing technologies. This methodology closely mimics a normal in-vivo environment and produces spheroids needed in cell transplantation therapies. This project will re ....Engineering floating liquid marbles for three-dimensional cell cultures. This project aims to understand the physics of three-dimensional cell cultures in a liquid marble floating on a liquid free surface. New methodology developed can produce these cell cultures without using matrices or scaffolds and with run-times well beyond existing technologies. This methodology closely mimics a normal in-vivo environment and produces spheroids needed in cell transplantation therapies. This project will resolve uncertainties in the underlying phenomena. The expected outcome should support future high quality cell cultures suitable for transplantation therapies.Read moreRead less
Adverse effects of sopite syndrome on occupants in wind-excited buildings. Current building motion design guidelines focus primarily on motion perception and complaint rates. However, wind-induced building motion can cause sopite syndrome or early onset motion sickness which adversely affects occupant wellbeing and work performance. This research aims to advance the understanding of the physiology of sopite syndrome, quantify the motion dosage that causes sopite syndrome and determine its advers ....Adverse effects of sopite syndrome on occupants in wind-excited buildings. Current building motion design guidelines focus primarily on motion perception and complaint rates. However, wind-induced building motion can cause sopite syndrome or early onset motion sickness which adversely affects occupant wellbeing and work performance. This research aims to advance the understanding of the physiology of sopite syndrome, quantify the motion dosage that causes sopite syndrome and determine its adverse effects on building occupants in real-world motion environments. This knowledge is expected to guide the formulation of building motion acceptability criteria based on safe motion exposure duration to facilitate the design of tall building that promotes population health and wellbeing and lifts work performance and productivity.Read moreRead less

Dynamic soil structure interaction. The aim of this project is to undertake a study of an important class of geotechnical problems in which systems composed of soil, structure and pore water are subjected to dynamic or impact loading. The outcomes will include safer and more efficient methods for designing geotechnical structures subjected to dynamic loading.

Predicting internal erosion in dams using real-time coupled experiments. Internal erosion causes nearly half of embankment dam failures globally.

Internal erosion causes nearly half of embankment dam failures globally. This project aims to develop a mechanics-based understanding of internal erosion to overcome the limitations of existing empirical approaches that do not capture the underlying physics. By innovatively coupling computational and physical experiments in real-time, this project expects to generate new insights that identify the factors leading to the initiation and continuation of internal erosion. The expected outcome of this project is a probabilistic framework able to predict the internal erosion process. This should significantly enhance and inform the design of erosion control measures and provide a holistic risk assessment for embankment dams.Read moreRead less
The design and construction of quality, sustainable and affordable pre-made housing in Australia - optimisation and integration. Historically, industrialised construction has resulted in an industrialisation of the parts, rather than an industrialisation of the ensemble. In contrast, this project will integrate architecture and engineering, as well as construction and development to optimise the ensemble, and deliver architectural quality in industrially produced affordable housing.

An earthquake shaking table to investigate soil-structure interactions: This project aims to develop Australia's most advanced earthquake shaking table. Earthquakes are a problem of great significance to Australia. Infrastructure in civil, transport, mining and energy sectors may be at an unacceptable risk of damage under earthquake loading as current design practices do not account for the interaction between infrastructure and the ground under such loading. The shaking table will simulate earthquakes and enable controlled testing of three-tonne models of foundation and soil-structure interaction systems typical of Australia's infrastructure. The discoveries made are expected to be integral to the modernisation of Australia's seismic design standards so that earthquake-induced damage and risk exposure can be minimised.Read moreRead less
