- Description
- The paper describes the development of a computational method to predict the strength for non-load bearing unreinforced masonry (URM) walls subject to two-way bending considering unit-to-unit spatial variability of the material properties of mortar joints and bricks. The study involves conducting numerical simulation of full sized walls subject to two-way bending using stochastic analysis in the form of Monte Carlo simulations and comparing the results with experimental work. A 3-D nonlinear Finite Element Analysis (FEA) is used to study how the spatial variability of material properties affects the wall failure progression. The numerical results are compared to literature experimental results in terms of the wall failure progression and wall capacity. It is shown that the model which considers the spatial variability of brickwork can capture the failure patterns and predict the cracking and ultimate loads for walls with two-way bending.
