“…Therefore, the wall elements shown in Figure 1 cause the wall to be anisotropic, since they have different material properties [1]. In this study, the modulus of elasticity in the wall structure was obtained by taking into consideration the change in the thickness of the mortar [2]. Material constants in both directions were obtained by using the stressstrain relations of the typical composite wall element in the plane stress effect.…”

The aim of this study is to investigate the effect of mortar/brick thickness ratio, brick configuration on the masonry stresses and on masonry structure modelling. Different mortar/brick thickness ratios are micro-modelled by using stress-strain relationship. The results of these models are used to obtain the material properties of anisotropic macro-models in vertical and horizontal directions. The sample unreinforced masonry structures are simulated by the SAP2000 software using anisotropic material properties. In general masonry structures are composite materials that consists of brick and mortar. The main goal in modelling is to simulate a model that behaves close to the real structure as much as possible. Micro-modelling of masonry structure by considering its components individually is more realistic but not practical for large scale structures. In order to overcome this problem, macro-modelling is used in literature. Macro-model is obtained by smearing out the material properties of the micro-model to an anisotropic continuum material. Currently, most engineers simply analysis masonry structures with isotropic modelling in practice. However, presence of head and bed mortar joints in the construction of masonry causes the masonry to be anisotropic. Anisotropic modelling of a large scale structure does not need unreasonable effort as in micro-modelling and can be used instead of isotropic modelling easily in practice. Considering the horizontal and vertical loads in the plane, some wall types with rectangular cross-section, rectangular and arches cross-sections cavities were modeled as anisotropic and the effect of anisotropic material was investigated. In terms of displacements, an isotropic model and anisotropic models were found to be close to each other. However, when examined in terms of stresses, the maximum and minimum stresses in the masonary structure were changed.

As is known, the masonry structures, together with the main structural materials, such as stone or brick, consist of mortar material which serves as the adhesive between these materials. In general, the mechanical properties of brick, stone and mortar materials are different. However, they have been used throughout history and have been the unchanging materials used in masonry structures. The structural walls are formed by the heterogeneous joining of two materials with different mechanical properties. However, these heterogeneous structural elements are generally considered homogeneous for ease of calculation. In this study, the effects of different joint thicknesses on masonry structures on minarets structure were investigated. Changes in structure behaviour were investigated by using different material properties to a masonry minaret structure. By examining these differences, the effect of isotropic or anisotropic modelling on the result, the effect of mortar thickness on the result was compared and the results were interpreted.
