ARC Research Hub for Advanced Solutions to Transform Tall Timber Buildings. This hub aims to develop skills, knowledge and resources for novel designs of tall timber buildings that incorporate architectural, engineering and sustainability drivers while meeting regulatory constraints. The project aims to develop innovative engineering solutions that address crucial barriers to the use of structural timber in the fast growing and extensive medium-rise tall buildings market where timber is, on many counts, the ideal construction material. It is expected that eliminating these barriers will open a new market for novel technologies and methods generated through this work.Read moreRead less

This project aims to deliver a novel composite steel–timber system that alleviates many of the environmental concerns of the industry, while improving efficiency by using lighter materials. It aims to develop a unique composite system comprised of steel I-section beams and prefabricated timber slabs, with shear connection being provided by bolting or screws. The project plans to assess the structural system experimentally and numerically, and to craft gu ....Composite steel-timber structural system. This project aims to deliver a novel composite steel–timber system that alleviates many of the environmental concerns of the industry, while improving efficiency by using lighter materials. It aims to develop a unique composite system comprised of steel I-section beams and prefabricated timber slabs, with shear connection being provided by bolting or screws. The project plans to assess the structural system experimentally and numerically, and to craft guidelines for the safe and efficient design of these members. The novel lightweight composite system would enhance the speed of construction, allow for deconstructability and reuse and, because plantation timber sequestrates carbon dioxide, have a low carbon footprint.Read moreRead less
The effect of tunelling on existing rock bolts. As more underground facilities such as rail, road, sewerage and service tunnels are constructed in our major cities, more and more frequently new tunnels have to cross over or run alongside existing tunnels. As the roofs of tunnels are generally supported by rock bolts and lined with shotcrete, the support system can be damaged by the rock movements caused by the excavation of the new tunnel. Little research has been carried out on this problem, an ....The effect of tunelling on existing rock bolts. As more underground facilities such as rail, road, sewerage and service tunnels are constructed in our major cities, more and more frequently new tunnels have to cross over or run alongside existing tunnels. As the roofs of tunnels are generally supported by rock bolts and lined with shotcrete, the support system can be damaged by the rock movements caused by the excavation of the new tunnel. Little research has been carried out on this problem, and so often expensive deviations have to be made to tunnels to avoid going near existing ones. The proposed research will provide numerical tools to allow prediction of loads induced into rock bolts by nearby tunnels, leading to more economical and safer tunnel design.

Enhanced Analysis of Time Dependent Viscous Behaviour of Soft Clay. Often post construction settlements of structures overlying clayey soils have been observed to be more than those predicted, or the predicted rate of settlement is not correct. The main benefit of this research is providing an accurate but simplified approach, which can be used by practicing engineers to predict the post construction settlement of structures in the design phase of construction projects. The community can conside ....Enhanced Analysis of Time Dependent Viscous Behaviour of Soft Clay. Often post construction settlements of structures overlying clayey soils have been observed to be more than those predicted, or the predicted rate of settlement is not correct. The main benefit of this research is providing an accurate but simplified approach, which can be used by practicing engineers to predict the post construction settlement of structures in the design phase of construction projects. The community can considerably benefit from the findings of this project including safer structures, significant reduction in the future maintenance costs and enhancing the performance of bridges, buildings, roads, railways and dams with less cracks and differential settlement.Read moreRead less

Stabilization of railway subgrade by lime-flyash slurry injection. The rail network in Australia provides a major transport route for commuters as well as transportation of goods. The subgrade of railway track should provide adequate support for the overlying ballast and capping layers. Hence, a poor subgrade always results in track problems associated with uneven track, fouled ballast, and misalignment of the track. This project will investigate in detail the fundamental mechanisms and key para ....Stabilization of railway subgrade by lime-flyash slurry injection.

The subgrade of railway track should provide adequate support for the overlying ballast and capping layers. Hence, a poor subgrade always results in track problems associated with uneven track, fouled ballast, and misalignment of the track. This project will investigate in detail the fundamental mechanisms and key parameters involved in the improvement of subgrade soil by injecting lime-flyash slurry. This project will develop an improved design procedure for lime-flyash slurry injection in the field based on experimental and numerical modelling.Read moreRead less

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.

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
