Comparison of Masonry Wall Modelling Approaches Under In-plane Monotonic Load and Cyclic Load
Masonry structures are widespread around the world due to their relative low cost, availability of raw materials and ease of construction. The prediction of structural masonry behaviour is complex, especially under extreme loading conditions such as earthquake excitation. Nowadays, numerical simulations are used in many engineering applications including masonry. In this study, a numerical 3 dimensional model of a masonry wall was developed for monotonic and cyclic loading. The cyclic load was applied continuously and repeatedly on the masonry wall model to observe the failure. For modelling, first, different numerical modelling approaches and failure modes of unreinforced masonry walls were studied. Two techniques were mainly considered for modelling: (a) micro modelling and (b) macro modelling. Micro modelling further studied as simplified micro modelling and detailed micro modelling. ABAQUS software was chosen for the numerical modelling due to its powerful engineering simulation ability of analysing the masonry wall in both the linear and the nonlinear regions. The validity of the model was demonstrated by simulating the linear and nonlinear response and failure mechanism of a cyclically loaded masonry wall tested experimentally in previous studies. Finally, the validated numerical model was used to investigate the much-needed behaviour of masonry walls under different extreme loading conditions.
