Abstract
Micro, simplified micro and macro modelling are used for the numerical modeling of the masonry. In this study, the efficiency of a 3-dimensional fixed smeared crack model in the micro modelling of masonry walls is investigated. For this purpose, the experimental results of the masonry walls called as the JD6 and JD7 Eindhoven walls are selected. 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. Interface element is not use at between brick and mortar. Predictor-corrector technique used for nonlinear analysis. Numerical and experimental results are compared in terms of the base shear-peak displacement curve and the crack regions obtained in the walls. Good approximation are obtained between experimental and numerical results with regard to ultimate base-shear force obtained. Some differences are determined between experimental and numerical results with regard to threshold displacement value that calculated versus ultimate base-shear force.
