Long-term behaviour of thin-walled concrete curved members strengthened with externally bonded composite materials. Concrete arches and domes are prone to catastrophic failures which involve loss of life and limb, and many global iconic structures are of this form. When subjected to creep, shrinkage and thermal effects, their behaviour is non-linear and complex.

Concrete arches and domes are prone to catastrophic failures which involve loss of life and limb, and many global iconic structures are of this form. When subjected to creep, shrinkage and thermal effects, their behaviour is non-linear and complex. This proposal will keep Australian research at the forefront by developing a fundamental understanding of these structural forms over time, when strengthened with externally-bonded composite materials in an innovative retrofit procedure. It encompasses the priority goal of frontier technologies for building and transforming Australian industry, will lead to valuable guidance for engineers, and will contribute to the training of skilled PhD scholars.Read moreRead less
Composite Beams using Fibre Reinforced Concrete (FRC) Profiled Slabs. The Australian construction industry is currently introducing long-span trapezoidal profiled steel sheeting for the composite floor slabs in composite steel-concrete framed buildings, in order improve efficiency and economy. When the ribs in the sheeting are orthogonal to the steel beam (the secondary beam), the integrity of the shear connection between the steel beam and the composite slab is compromised by premature failur ....Composite Beams using Fibre Reinforced Concrete (FRC) Profiled Slabs. The Australian construction industry is currently introducing long-span trapezoidal profiled steel sheeting for the composite floor slabs in composite steel-concrete framed buildings, in order improve efficiency and economy. When the ribs in the sheeting are orthogonal to the steel beam (the secondary beam), the integrity of the shear connection between the steel beam and the composite slab is compromised by premature failures. This project aims to research the innovative use of steel fibre reinforced concrete in these slabs, which has been shown (at UNSW and elsewhere) in other applications to possess superior strength properties when subjected to a variety of loading regimes.Read moreRead less
Long Term Behaviour Of Composite Steel-Concrete Beams And Its Effect On Composite Dynamic Response. Composite steel-concrete construction has proven to be a most prolific area of research over the last few decades with Australian researchers at the forefront in the field internationally. Despite this and the great significance of the problem to the Australian building industry (in 2000-2001 alone Australia spent 17.5 billion dollars on heavy engineering infrastructure development), there appears ....Long Term Behaviour Of Composite Steel-Concrete Beams And Its Effect On Composite Dynamic Response. Composite steel-concrete construction has proven to be a most prolific area of research over the last few decades with Australian researchers at the forefront in the field internationally. Despite this and the great significance of the problem to the Australian building industry (in 2000-2001 alone Australia spent 17.5 billion dollars on heavy engineering infrastructure development), there appears to be no systematic study of time effects, such as creep and shrinkage, on the static and dynamic response of composite beams. This project will explore these phenomena, both theoretically and experimentally, leading to development of valuable theoretical models and design aids for practicing engineers.Read moreRead less

There is an urgent need to rehabilitate existing structures that are considered inadequate in strength and serviceability. Frontier strengthening technologies (such as external post-tensioning and plate bonding) using conventional and advanced materials are being currently developed in Australia by different groups, but as yet not in a coordinated manner. The aim of this network is to bring together a multi-disciplinary team with complementary strengths to provide an integrated solution for rehabilitation of structures. The core of the network focuses on design tools, linking the various technologies to provide appropriate rehabilitation and understanding of life cycle demands for major infrastructure.Read moreRead less

The project provides a comprehensive physical understanding on thermal de-consolidation and re-consolidation processes in advanced thermoplastic composites during re-heating/cooling processes, such as thermoforming and joining. Mechanistic models based on theoretical analysis, experimental studies and computational modelling will be established to provide a unified approach to predict de-consolidation and re-consolidation processes. Optimum processing-windows will be established, with which the undesired deterioration in material meso-structures and mechanical performance due to de-consolidation is effectively minimised. The outcomes of the project will fill the gap in the knowledge for thermoplastic composite processing and will improve the integrity of thermoplastic composite structures in practical applications.Read moreRead less
