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
Fatigue Behaviour of Dragline Tubular Structures. Fatigue failure is a major concern for dragline tubular structures. Several catastrophic collapses of such structure occurred. The fatigue behaviour of such large tubular structures is unknown. Fatigue cracks were observed in many existing draglines. The latest international design codes are inadequate to address this issue. The project will develop reliable methodologies for design, inspection, strengthening and assessment of such structures. Th ....Fatigue Behaviour of Dragline Tubular Structures. Fatigue failure is a major concern for dragline tubular structures. Several catastrophic collapses of such structure occurred. The fatigue behaviour of such large tubular structures is unknown. Fatigue cracks were observed in many existing draglines. The latest international design codes are inadequate to address this issue. The project will develop reliable methodologies for design, inspection, strengthening and assessment of such structures. The outcome will be reduced manufacturing and operational costs and a reduced catastrophic failure risk. This will increase the international competitiveness of Australian mining industry. Several other industry sectors will be benefited from the technology developed in this project.Read moreRead less
Topological Optimization of Load-carrying Structural Systems with Repetitive Geometrical Patterns. Periodic structures are increasingly used in the design of the structural systems or sub-systems of buildings, bridges, aircraft, motor vehicles etc. The duplication of identical or similar modules significantly reduces the production cost and greatly simplifies the assembly process. In many cases periodic structures are also selected for their distinctive aesthetic appeal.
