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
Structural Systems with Hollow Flange Sections in Cold-Formed Steel. Palmer Tube Mills have created a new range of hollow flange sections in cold-formed steel manufactured with the unique dual resistance welding process for use in the construction industry. The new sections combine the properties of hot-rolled open sections and cold-formed sections to create more structurally efficient sections. These new sections experience some unique and specific failure modes that are not considered in cur ....Structural Systems with Hollow Flange Sections in Cold-Formed Steel. Palmer Tube Mills have created a new range of hollow flange sections in cold-formed steel manufactured with the unique dual resistance welding process for use in the construction industry. The new sections combine the properties of hot-rolled open sections and cold-formed sections to create more structurally efficient sections. These new sections experience some unique and specific failure modes that are not considered in current design standards. This project will investigate these failure modes to devise efficient and safe guidelines for their structural design. 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
Retrofitting unreinforced masonry walls with fibre reinforced polymer strips. An efficient technique for increasing the safety of existing masonry structures under earthquake (and other) loading will be developed. This is essential to the safe continued use of existing infrastructure (avoid replacement = economic benefit). This new technique addresses many shortcomings in existing alternatives (increased performance, reduced cost). This research is particularly important in Australia where unrei ....Retrofitting unreinforced masonry walls with fibre reinforced polymer strips. An efficient technique for increasing the safety of existing masonry structures under earthquake (and other) loading will be developed. This is essential to the safe continued use of existing infrastructure (avoid replacement = economic benefit). This new technique addresses many shortcomings in existing alternatives (increased performance, reduced cost). This research is particularly important in Australia where unreinforced masonry accounts for most domestic construction, much light commercial infrastructure, as well as many heritage and post-disaster buildings. It also reinforces Australia's high international standing in developing innovative retrofitting alternatives using advanced materials in this rapidly developing area. Read moreRead less
