Displacement -Based Earthquake Design Of Urm Walls

Grant number: DP0450933


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.
