Measuring highly resolved flow and sound in Australia's largest wind tunnel. Monash and RMIT Universities have developed an aero-acoustic facility of international standing to study flows around vehicles, buildings and structures.

Monash and RMIT Universities have developed an aero-acoustic facility of international standing to study flows around vehicles, buildings and structures. This is based around the largest wind tunnel in the Southern Hemisphere, which provides a National facility crucial to the development of a competitive automotive industry. To achieve the next stage of research development, velocities and acoustic fields need to be measured with increased accuracy and spatial resolution than currently available. Given the physical scale of the facility, it is proposed to achieve this with an automated measurement system, which will also be integral to future research programs.Read moreRead less

Shape changing structures play an imperative role in aerospace, automobile, energy and other industries. This project aims to develop novel concepts extracted from nastic motion in plants and relevant computational algorithms for the design of nastic cellular structures with osmotic actuation.

This project will develop an innovative new method based on coupled finite element and scaled boundary finite-element analysis for predicting the ground vibrations induced by road traffic and underground or surface trains. The method will have immediate application in transportation engineering to predict traffic-induced ground vibrations, in geotechnical engineering to design isolation trenches and wave barriers to dissipate wave propagation, and in structural engineering to estimate in-structure vibration level and design isolators for sensitive equipment housed within. The technique will involve fundamental advances in the scaled boundary finite-element method, as calculations will be performed in a moving reference frame.Read moreRead less
Time-dependent dynamic, creep and shrinkage response of curved structural members. This project concerns curved structural members, such as bridge beams, that are subjected to dynamic excitation and to concrete shrinkage and creep. Hitherto, unified formulations for the structural behaviour of these members have not been properly developed. The proposal seeks to build on a previous ARC DP of the investigator that produces significant results for static loading, by developing a sophisticated meth ....Time-dependent dynamic, creep and shrinkage response of curved structural members. This project concerns curved structural members, such as bridge beams, that are subjected to dynamic excitation and to concrete shrinkage and creep. Hitherto, unified formulations for the structural behaviour of these members have not been properly developed. The proposal seeks to build on a previous ARC DP of the investigator that produces significant results for static loading, by developing a sophisticated methodology to handle non-static dynamic loading and for shrinkage and creep. It will develop advanced mathematical tools to enable the safe and efficient design of a multiplicity of structures that is of benefit to on and offshore Australian technology.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. 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.

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

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

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
