Masonry is one of the earliest structure types of the history. These walls are composite structures that can be modeled using advanced techniques such as numerical methods. Modeling of the masonry structures is a necessary to understand their structural behavior. Designing of masonry structures and verification of experiments on the masonry structures, numerical models can be used efficiently. The finite element analysis (FEA) is a robust numerical technique to analyze masonry structures. In this paper, nonlinear behaviors of heterogenous masonry walls under the effect of in-plane loads are
numerically modeled and analyzed with ANSYS software [1]. The masonry units such as bricks, stones or etc. and mortar between the masonry walls are modelled as detailed heterogenous modelling. A parametric analysis is performed to investigate the structural design parameters of masonry walls via nonlinear finite element analysis. The effect of aspect ratio on the masonry wall, the effect of mortar thickness and masonry units are analyzed numerically based on finite element method. The Willam-Warnke failure hypothesis, a suitable hypothesis for materials which have high compressive strength but having low tensile strength, is used to determine the material properties of the masonry wall. The combination of selected modeling technique, the material model and the fracture hypothesis are successfully performed for masonry wall models. Remarkable results were obtained for investigation of design parameters of masonry walls. Strength values of the walls are determined as result of the parametric analysis on the walls. By using the finite element modeling approach presented in this study, masonry walls which have distinct design parameters can be successfully and practically analyzed.
