Progressive failure of masonry shear walls ¨C a distinct element approach
Masonry is not a simple material. The influence of mortar joints as a plane of weakness is a significant feature and this makes the numerical modelling of masonry very difficult especially when dynamic (seismic) analysis is involved. In the past few years, an analytical model based on Distinct Element Method (DEM) has been developed and applied to simulate the in-plane shear behaviour of unreinforced masonry walls. In DEM, a solid is represented as an assembly of discrete blocks. Joints are modelled as interface between distinct bodies. It is a dynamic process and specially designed to model the behaviour of discontinuities. The numerical solutions obtained from DEM are validated by comparing the results with those obtained from existing experiments and finite element modelling. A parametric study is also performed to test the sensitivity of the model with various damping schemes.
Dr Yan Zhuge has a BEng (Hons) in Civil Engineering and a Masters in Structural Engineering from Beijing, China, a PhD in Structural Engineering from Queensland University of Technology (QUT), Australia. Yan currently is a professor in structural engineering at the University of Southern Queensland, Australia. Her research interests include sustainable construction materials, fibre composite structures, seismic retrofitting of unreinforced masonry structures using fibre reinforced polymer (FRP) and nonlinear analysis and modelling of masonry structures. She has published more than 130 technical papers in the referred international journals and conferences and has been invited as a keynote speaker at several international conferences.
