The Influence of Cement Type, Age and Curing Conditions on the Flexural Capacity of Masonry Walls. The use of cements containing waste products such as fly ash and blast surface slag has increased markedly. This has desirable environmental and economic consequences, but the influence of these cements on the bond strength of masonry constructed from mortars containing these cements is unknown and in urgent need of clarification. This investigation studies this effect as well as the influence of ....The Influence of Cement Type, Age and Curing Conditions on the Flexural Capacity of Masonry Walls. The use of cements containing waste products such as fly ash and blast surface slag has increased markedly. This has desirable environmental and economic consequences, but the influence of these cements on the bond strength of masonry constructed from mortars containing these cements is unknown and in urgent need of clarification. This investigation studies this effect as well as the influence of age and curing conditions on masonry flexural strength at both a fundamental and applied level, thus allowing the impact of the use of mortars containing these cements on actual building performance to be assessed.Read moreRead less
Design of Welded Steel Tubular Connections. Steel tubes are widely used in building, road transportation, defence, recreation, and agriculture industries. The proposed program will develop static design procedures for welded tubular connections to ensure safe and economic structures. The program will also investigate the behaviour of a popular tubular connection utilizing very high strength steel tubes to extend the existing design scope and enhance the utilization of Australian produced innovat ....Design of Welded Steel Tubular Connections. Steel tubes are widely used in building, road transportation, defence, recreation, and agriculture industries. The proposed program will develop static design procedures for welded tubular connections to ensure safe and economic structures. The program will also investigate the behaviour of a popular tubular connection utilizing very high strength steel tubes to extend the existing design scope and enhance the utilization of Australian produced innovative tubular sections. The notch toughness of steel tubes will also be investigated to avoid fracture failure of welded connections under dynamic loading. The program will build strong ongoing collaboration between University of Toronto and Monash University.Read moreRead less
Interaction of Local and Distortional Buckling in Thin-Walled High Strength Steel Sections. Recent research at the University of Sydney has shown that the local and distortional buckling modes in thin-walled high strength steel sections may have adverse interaction. Cold-Formed steel sections of this type are used in residential construction, ceiling systems, partitioning systems in offices and other light gauge applications. The project will develop mathematical models of the interaction beha ....Interaction of Local and Distortional Buckling in Thin-Walled High Strength Steel Sections. Recent research at the University of Sydney has shown that the local and distortional buckling modes in thin-walled high strength steel sections may have adverse interaction. Cold-Formed steel sections of this type are used in residential construction, ceiling systems, partitioning systems in offices and other light gauge applications. The project will develop mathematical models of the interaction behaviour of sections of this type for a wide range of section geometries. A major outcome will be design methods which accurately quantify the interaction behaviour based on the models. Testing will be undertaken to support the theoretical developments and to calibrate the design models.Read moreRead less
