Investigation of three dimensional fixed smeared crack model in micro model analysis of the masonry walls

In this study, the effectiveness of 3-dimensional smeared crack model in the micro-model analysis of masonry walls is investigated. The concrete model with three parameters which special case of William Warnke model is used to calculate the nonlinear behavior of mortar and brick regions of this wall. For numerical analyses, SOLID65 concrete elements in ANSYS finite element software are selected. For comparison of the numerical results, the base shear force-top displacement curve and the fracture regions obtained from the experimental results of the Eindhoven walls which JD4, JD6 and JD7, are used. In first phase of the numerical solutions, the effects on the solutions of compressive strength of the bricks, tensile strength of the mortar and shear transfer coefficient are investigated. In the second phase of the numerical solutions, the mortar is discretized two different material as bed and head regions. The effects on the numerical solutions of the two different mortar materials are also investigated.
