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.

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

Research Network for Rehabilitation of Structures Using Advanced Materials and Frontier Technologies. 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.

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
Development of Viable Geopolymer. This project aims to improve the manufacture of geopolymer. Geopolymer (‘green cement’) is produced by alkali activation of fly ash and is a sustainable, low carbon dioxide alternative to conventional cement. Evaluation of raw materials and ensuring reliable performance are critical issues in geopolymer manufacture. The project aims to understand the geopolymerisation process and the behaviour of fly ash and activator in the process. It plans to establish a reac ....Development of Viable Geopolymer.

Evaluation of raw materials and ensuring reliable performance are critical issues in geopolymer manufacture. The project aims to understand the geopolymerisation process and the behaviour of fly ash and activator in the process. It plans to establish a reactivity index to quantitatively evaluate fly ash and match it with activator to achieve efficient activation with predictable properties. The project is expected to result in a scientific tool to assess fly ash suitability and a method to design and produce viable geopolymers.Read moreRead less
