This project will investigate the structural behaviour, strength and reliability of innovative veneer based composite structures manufactured from waste hardwood plantation thinning. Unlike sawn timber, these structures have efficient cross-sectional shapes and can be made in sizes currently not available in timber. Yet due to the proportion of natural singularities in the material, the variability in their mechanical properties is not fully understood and their actual strength cannot be accurately predicted. Additionally, their exact structural behaviour and failure modes require attention. This project aims to fill these gaps in knowledge and ultimately establish probability-based limit state design criteria for these sections.Read moreRead less

This project aims to investigate the structural behaviour of innovative hybrid Fibre Reinforced Polymer - Timber Composite (FRPTC) sections manufactured from small 'sawlog' timber. These FRPTC sections are made by taking advantage of the orthotropic material properties and, unlike sawn timber, these structures have efficient cross sectional shapes and can be made easily in different sizes to match the requirements. Even though preliminary studies have shown promising results, behaviour of these FRPTC sections are not yet fully understood. This project aims to investigate the behaviour of these novel FRPTC sections and to develop numerical models to allow wide usage of these sections.Read moreRead less

Light steel roof and wall systems under combined wind and bushfire actions. The project aims to investigate the complex behaviour of light cold-formed-steel roof and wall systems involving localized failures under the combined action of wind and bushfire using wind suction tests at elevated temperatures combined with advanced numerical modelling. It will generate new knowledge of the behaviour and strength of cold-formed-steel roof and wall systems under bushfire conditions. Expected outcomes in ....Light steel roof and wall systems under combined wind and bushfire actions. The project aims to investigate the complex behaviour of light cold-formed-steel roof and wall systems involving localized failures under the combined action of wind and bushfire using wind suction tests at elevated temperatures combined with advanced numerical modelling. It will generate new knowledge of the behaviour and strength of cold-formed-steel roof and wall systems under bushfire conditions. Expected outcomes include new design models for wind, bushfire and cold-formed-steel Standards. This will significantly improve the bushfire safety of buildings, since non-combustible steel roof and wall systems are used as building envelopes in bushfire prone areas, but are not designed to withstand recently discovered bushfire-enhanced winds.Read moreRead less
Fibre-Reinforced Timber for Novel Hybrid Folded Thin-Walled Structures. This project proposes novel manufacture and analysis methods for fibre-reinforced polymer (FRP) hybrid sections. FRP composites have gained wide acceptance within the civil engineering community.

This project proposes novel manufacture and analysis methods for fibre-reinforced polymer (FRP) hybrid sections. FRP composites have gained wide acceptance within the civil engineering community. All-FRP systems typically use thin-walled profiles based on steel sections, but existing manufacturing technologies are unable to optimise material usage. Hybrid systems combine FRP with traditional materials for optimum structural performance and so are often more economical than all-FRP systems. This project aims to develop an effective way to analyse, manufacture, and design FRP-based hybrid thin-walled structural members and optimise performance against buckling failure modes. The technology developed in this project would support the development of advanced low-cost FRP structural systems.Read moreRead less

This project plans to develop design rules and mullion profiles to support the use of façades using aluminium members with complex shapes. The façade is of great importance to the structural safety, energy efficiency and aesthetics of a building. Commonly used façade systems are made of glass supported by aluminium mullions with complex shapes. Current aluminium design standards do not consider the instability and failures caused by wind actions on facades using such complex aluminium members. This project aims to conduct full-scale tests and develop advanced numerical models to resolve several critical problems and identify designs with superior wind resistance. Based on this, the project aims to provide innovative, accurate and safe design rules for the façade engineering profession and building industry.Read moreRead less
