Modeling and analysis of masonry buildings is a challenging task due to several reasons. First, structural walls constitute a non-homogeneous continuum with highly nonlinear and unpredictable behavior when compared to the material characteristics of basic ingredients of these walls; i.e., masonry units and mortar. Moreover, it is not easy to determine the material properties of the ingredients due to non-standard production of masonry units and inconsistency in the workmanship. As the last but not least, the structural integrity and the connections between structural units like walls, piers, spandrels and floors may be complex or not well-defined, especially in the presence of openings. This issue generally hinders the development of a standard structural model as in the case of frame structures due to complicated load transfer paths. Considering all of the aforementioned challenges of masonry modeling and analysis, this study will focus on different modeling strategies and approaches that have been used in the past for design and assessment of unreinforced masonry buildings. Special attention will be given to equivalent frame approach, which is a simplified approach that has been added to the latest version of the Turkish Seismic Code. The pros and cons of this method are evaluated in comparison to other available methods and finally some recommendations are proposed in order to enhance the design principles regarding unreinforced masonry buildings in the next version of the seismic code.
