Abstract

Masonry structures are constructed by joining masonry units (brick, stone, marble etc.) with mortar. Various methods are used for modelling of masonry walls of the structures. Micro modelling and Macro modelling are two diverse modelling techniques. In this study, these two modelling strategies are analyzed on a solid unreinforced masonry shear wall numerically. The models are implemented in ANSYS software to simulate the structural behavior of a tested wall in literature. The homogenization technique is applied to obtain the material parameters used in the macro model. Brick and mortar are modelled separately in the micro model. Stresses occurring in the walls under the effect of in-plane loads are investigated. The propagations of the cracks on the walls are analyzed numerically. The results obtained in the micro modelling and macro modelling are in consistent with the experimental study in the literature. However, macro modelling and micro modelling represent strictly disparate behavior in the material identification, and crack propagations.
