PROBABILISTIC BRIDGE STRUCTURE CONDITION ASSESSMENT AND LOAD CARRYING CAPACITY PREDICTION. Bridge failures have occasionally been reported around the world. Condition assessment of bridges is vital to maintain their safety. It is difficult to assess quantitatively the deterioration and damage using traditional methods. Vibration-based methods are very sensitive to noise in vibration measurement and error in finite element modelling.

Bridge failures have occasionally been reported around the world. Condition assessment of bridges is vital to maintain their safety. It is difficult to assess quantitatively the deterioration and damage using traditional methods. Vibration-based methods are very sensitive to noise in vibration measurement and error in finite element modelling. This project will study the effects of measurement noises and finite element model errors on bridge condition assessment, and develop improved techniques for predicting load carrying capacities of bridges. The technique developed will be applied to Main Roads WA bridges, will also be applicable to the assessment of other types of structures.Read moreRead less
Analysis and design of interlocking brick system against earthquake loading. This project aims to develop optimised interlocking bricks to resist static and earthquake loads.

This project aims to develop optimised interlocking bricks to resist static and earthquake loads. Using conventional bricks in masonry construction requires skilled labour to connect bricks with mortar. Development of interlocking bricks for mortarless connection has been attracting great interest because the easy alignment improves construction efficiency and quality. Interlocking also leads to better mechanical performance of the resulting structures. This project will have significant impact on construction technology and the Australian masonry industry, and greatly improve the competitiveness of the Australian construction industry in the international market.Read moreRead less
Numerical and experimental study of pounding damage of adjacent bridge structures to spatially varying earthquake ground motions. Bridge damage in an earthquake prevents rescue personnel and equipment from quick access to the affected area. Repairing or replacing a damaged bridge and the increased commuting time after the earthquake may have a significant impact on the economy and life of the general public. This project will develop techniques for earthquake-resistant bridge design.
Geotechnical and soil-structure interaction properties of soils in Perth CBD. A new underground railway (City Project) will shortly begin construction in Perth CBD.

This construction, and its associated high level of monitoring instrumentation, offers a unique opportunity for an extensive and thorough examination of the mechanical properties of Perths soils. The research results emanating from the proposed combination of field monitoring, laboratory investigation and numerical analysis, will greatly improve the reliability (and hence cost) of future foundation and basement designs in Perth and elsewhere.Read moreRead less
Assessment of structural integrity and deterioration of masonry walls. Brickwork for housing and medium-rise buildings is a traditional material, also much used for modern construction, with aesthetic appeal and modest cost. However, building regulators and others are increasingly concerned about evidence of slow building deterioration, particularly of older buildings. This increases public safety risks, even under normal conditions and more so under high winds or earthquake-induced ground-shaki ....Assessment of structural integrity and deterioration of masonry walls. Brickwork for housing and medium-rise buildings is a traditional material, also much used for modern construction, with aesthetic appeal and modest cost. However, building regulators and others are increasingly concerned about evidence of slow building deterioration, particularly of older buildings. This increases public safety risks, even under normal conditions and more so under high winds or earthquake-induced ground-shaking. This project will help address this issue. It will obtain unbiased evidence of typical masonry building deterioration. It will couple this with mathematical modelling and state-of-the-art non-destructive visual and dynamic techniques to develop tools for making fast, low-cost practical building risk assessments.Read moreRead less
Study of Blast Resistance Capacity of Basalt Fibre Strengthened Structures. This project plans to investigate the dynamic response of basalt fibre reinforced polymer (BFRP) reinforced structures against blast loading. Critical infrastructures such as embassy buildings, high-rise building, bridges and defence facilities are intensively targeted by increasing terrorist activities or accidental explosions. BFRP is a promising material for such structures because it is cheaper than carbon fibre and ....Study of Blast Resistance Capacity of Basalt Fibre Strengthened Structures. This project plans to investigate the dynamic response of basalt fibre reinforced polymer (BFRP) reinforced structures against blast loading. Critical infrastructures such as embassy buildings, high-rise building, bridges and defence facilities are intensively targeted by increasing terrorist activities or accidental explosions. BFRP is a promising material for such structures because it is cheaper than carbon fibre and has better physico-mechanical properties than glass fibre. However, there has been very limited study of the effectiveness of BFRP strengthening on structure blast-loading resistant capacities. This project aims to perform numerical and experimental studies to support the development of BFRP applications in strengthening structures against blast loads.Read moreRead less
An innovative light weight composite panel system for high speed modular construction. This project aims to develop an innovative composite panel system using aerated geopolymer and a thin high strength steel casing. The new panel system aims to have a number of significant enhancements compared to traditional panels in terms of load resistance, much lower carbon footprint and life-cycle costs.

This project aims to develop an innovative composite panel system using aerated geopolymer and a thin high strength steel casing. The new panel system aims to have a number of significant enhancements compared to traditional panels in terms of load resistance, much lower carbon footprint and life-cycle costs. It aims to offer desirable properties, such as being light-weight, easy to construct, economical, recyclable and reusable. A significant gap in knowledge exists in the material and system behaviour of the aerated geopolymer and its fire performance. It is intended that a comprehensive research program will be carried out to address those challenges and to provide design guidelines to rapidly progress these technologies in Australia and overseas.Read moreRead less
Concrete Enriched with Carbon Nanotubes for Advanced Future Construction. This project aims to develop an advanced construction material based on enrichment of concrete with carbon nanotubes (CNT). Concrete, the most consumed construction material globally, is brittle and needs embedded steel reinforcement. Concrete enriched with CNT, one of the strongest known fibres, may partially replace conventional bulky and heavier steel reinforcement thereby creating economies (e.g. thinner section sizes) ....Concrete Enriched with Carbon Nanotubes for Advanced Future Construction. This project aims to develop an advanced construction material based on enrichment of concrete with carbon nanotubes (CNT). Concrete, the most consumed construction material globally, is brittle and needs embedded steel reinforcement. Concrete enriched with CNT, one of the strongest known fibres, may partially replace conventional bulky and heavier steel reinforcement thereby creating economies (e.g. thinner section sizes), and reduced carbon dioxide emissions by expending less steel and cement for construction. This project extends earlier research by the research team and aims to transform cement-CNT pastes into construction-scale concrete by resolving uncertainties associated with scaling.Read moreRead less
