Unlocking lab-to-field scaling in design for floating offshore structures. This project aims to develop rigorous, physics-based models to accurately predict hydrodynamics of floating offshore structures at different scales.

This project aims to develop rigorous, physics-based models to accurately predict hydrodynamics of floating offshore structures at different scales. The project will address the issue between laboratory-to-field scaling, a fundamental problem in fluid dynamics. This outcome will be achieved through the integration of numerical technology, with physical modelling and field data acquisition. The outputs from this project will reduce risks and improve operability of existing offshore structures, and lead to more efficient design for potential floating offshore projects. This will benefit the whole community of floating offshore structures and cement Australia’s place as a pioneer in offshore industry and emerging renewable energy sector.Read moreRead less
Marine vessel wave wake: Ferry operations in sheltered waterways. This project aims to address one of the biggest risk factors to the Sydney ferry system, by ensuring the waves that new ferries generate are minimised. This would reduce the impact on other users of this busy waterway or damage to the surrounding infrastructure or environment. Modernising Sydney’s fleet of iconic passenger ferries is an integral part of the New South Wales Government’s long-term transport master plan.

This project aims to address one of the biggest risk factors to the Sydney ferry system, by ensuring the waves that new ferries generate are minimised. This would reduce the impact on other users of this busy waterway or damage to the surrounding infrastructure or environment. Modernising Sydney’s fleet of iconic passenger ferries is an integral part of the New South Wales Government’s long-term transport master plan. The project is intended to predict the waves produced by any proposed ferry operation, allowing changes to be made to minimise waves during early planning stages. The new method for predicting the complex wave phenomenon is designed to provide more comprehensive and accurate assessments than conventional technologies.Read moreRead less

This project aims to create the computational models and methods needed to advance current understanding of musculoskeletal function during movement. Humans must maintain their capacity to move in order to maintain quality-of-life. Predictive modelling is potentially the most powerful approach for understanding musculoskeletal function during movement. Current computational methods are too slow and unreliable to deliver predictive simulations of movement using realistic models of muscle and joint anatomy. This project expects to create the next generation of methods and algorithms needed to enable predictive modelling of movement. Predictive simulations will provide new insights into how muscles stabilise and control movements of the spine, pelvis and lower limbs during daily activities such as walking.Read moreRead less

Progressive collapse resistance of concrete flat plate structures. This project aims to systematically and thoroughly investigate the progressive collapse mechanisms and resistance capacity of concrete flat plate structures.

This project aims to systematically and thoroughly investigate the progressive collapse mechanisms and resistance capacity of concrete flat plate structures. They represent one of the most common construction systems used worldwide in modern days, yet their progressive collapse mechanisms require attention and limited collapse prevention design guidelines are available. The outcomes are expected to broaden and deepen the existing theoretical framework and knowledge base, prevent injury and loss of life in both new and existing buildings. This is expected ultimately to contribute to the establishment of a set of collapse-resistant design guidelines for further development of relevant Australian and international standards.Read moreRead less

This project aims to develop a high-performance tool for the dynamic safety assessment of softening structures. The assessment of structures that exhibit softening, either at constitutive level or structural level, is essential for design and rehabilitation purposes, especially when the inevitable uncertainties in the system parameters need to be accounted for. This project aims to develop an advanced and unified framework that can model both stochastic and nonstochastic processes for these purposes. An advanced mixed finite element model underpins this framework, and both formulation and solution algorithms are based on mathematical programming formalism. The developed computational tool would be able to perform pure stochastic, pure nonstochastic, hybrid uncertain analyses and dynamic reliability assessment of structures.Read moreRead less
