Displacement-based assessment of the seismic resistance of unreinforced masonry buildings. Earthquakes have caused over $1,000 billion of damage and more than 100,000 deaths in the last decade. This devastation occurred mainly in unreinforced brick masonry (URM) buildings which constitute the bulk of the domestic building stock in low seismicity regions, including Australia. These buildings were designed to resist forces, not the displacements, caused by earthquake ground shaking. This projec ....Displacement-based assessment of the seismic resistance of unreinforced masonry buildings. Earthquakes have caused over $1,000 billion of damage and more than 100,000 deaths in the last decade. This devastation occurred mainly in unreinforced brick masonry (URM) buildings which constitute the bulk of the domestic building stock in low seismicity regions, including Australia. These buildings were designed to resist forces, not the displacements, caused by earthquake ground shaking. This project will develop a new displacement-based method for assessing the earthquake resistance of URM buildings. Research outcomes will be in the form of improved analytical methods for the design of new buildings and the seismic assessment and retrofit of existing buildings.Read moreRead less

In acknowledging that climate change is one of the greatest moral and economic challenges of our time, the federal Government is committed to Australia's internationally agreed target of limiting greenhouse gas emissions. In its efforts to achieve this, the Government is supporting various initiatives including the development of renewable energy technology. In Australia, buildings contribute almost one-quarter of our greenhouse gas emissions. This research will identify methods that assist in the nationwide uptake of sustainability practices, including the use of micro-generation technology, to help improve building performance and reduce greenhouse gas emissions.Read moreRead less
Behaviour of anchors in post-tensioned high-strength concrete slabs. Recently High-strength concrete(HSC) was introduced to minimise the time required for stressing the tendons in post-tensioned construction(PC), which is the preferred construction method for long span slabs in Australia and overseas. Although HSC is an obvious choice for this application, many failures have been observed in the live and dead end anchors of PC slabs and there is in fact very little understanding of relationships ....Behaviour of anchors in post-tensioned high-strength concrete slabs. Recently High-strength concrete(HSC) was introduced to minimise the time required for stressing the tendons in post-tensioned construction(PC), which is the preferred construction method for long span slabs in Australia and overseas. Although HSC is an obvious choice for this application, many failures have been observed in the live and dead end anchors of PC slabs and there is in fact very little understanding of relationships between specified concrete properties and performance. Through a systematic experimental and theoretical study, the behaviour of anchor regions of these slabs, including the reasons for failure will be investigated.Read moreRead less
Seismic performance of concrete beam-slab-column systems constructed with a re-useable sheet metal formwork system. When designing for earthquake induced loading it is very important to know the ductility and any other inherent deficiencies in structural systems under lateral deflections. The main purpose of this application is to investigate the seismic performance of an efficient beam-slab-column system constructed with a re-useable sheet metal formwork system, Corcon, which is becoming popula ....Seismic performance of concrete beam-slab-column systems constructed with a re-useable sheet metal formwork system. When designing for earthquake induced loading it is very important to know the ductility and any other inherent deficiencies in structural systems under lateral deflections. The main purpose of this application is to investigate the seismic performance of an efficient beam-slab-column system constructed with a re-useable sheet metal formwork system, Corcon, which is becoming popular in Australia and overseas. The proposed research will ultimately lead to revised design guidelines for these systems, suitable for local and overseas practice where different levels of seismicity occur.

Stochastic Modelling of Strength and Reliability of Masonry Walls Loaded in Flexure and Compression. For new construction, a more efficient use of structural masonry will mean that less material will be used when compared to masonry structures designed to existing design specifications. This will result in lower construction costs, reduced energy costs and could help contribute to an increase in building approvals. The ability to more accurately assess the safety of existing masonry structures m ....Stochastic Modelling of Strength and Reliability of Masonry Walls Loaded in Flexure and Compression. For new construction, a more efficient use of structural masonry will mean that less material will be used when compared to masonry structures designed to existing design specifications. This will result in lower construction costs, reduced energy costs and could help contribute to an increase in building approvals. The ability to more accurately assess the safety of existing masonry structures may allow authorities to avoid unnecessary demolition or rehabilitation of such structures. Such infrastructure includes much of Australia's domestic housing, light commercial structures, numerous heritage buildings, and many structures required to serve a post disaster function.Read moreRead less

Building energy consumption accounts for nearly 27% of all energy related greenhouse gas emissions. By 2010, emissions' from buildings is estimated to increase by 48% above 1990 levels. This projected trend is alarming given that Australia's obligation under the Kyoto Protocol is only 8% above 1990 levels. Renovation of existing buildings is necessary to achieve this target. Research will address this problem by providing principles, strategies and solutions demostrating improvement of environmental performance and cost benefits. The application of new principles will assist with transforming the building industry to meet Kyoto targets.Read moreRead less

The project will also develop new structural systems to utilise the unique properties of these sections.Read moreRead less
Displacement-based earthquake design of unreinforced masonry walls in two-way bending. Current design of unreinforced masonry (URM) buildings for earthquake loading is based on checking that the strength of walls and connections exceeds the earthquake-induced inertia forces. Conservative estimates of wall bending strength are used to account for the wide variability in the quality of masonry construction. This project proposes to develop a new "displacement-based" design methodology for URM wa ....Displacement-based earthquake design of unreinforced masonry walls in two-way bending. Current design of unreinforced masonry (URM) buildings for earthquake loading is based on checking that the strength of walls and connections exceeds the earthquake-induced inertia forces. Conservative estimates of wall bending strength are used to account for the wide variability in the quality of masonry construction. This project proposes to develop a new "displacement-based" design methodology for URM walls which is less conservative and more direct, reliable and easier to apply the the force-based method. Hence, this method offers substantical cost savings over current techniques for the assessment of the seismic vulnerability of URM walls in buildings.Read moreRead less
