Recent Mexican policies that promote the construction of housing units are aimed at the optimization of the scarce available spaces in large cities. Within this context, the construction of tall buildings is being considered. Tall masonry buildings will likely have slender walls in their structural system. An increase in the slenderness ratio of a wall results in a change of its behavior when subjected to lateral loads; evolving from a shear dominated response to a bending dominated one. This paper provides qualitative and quantitative elements that allow for a discussion of the possibility of constructing tall confined masonry buildings in seismic zones. To achieve this, a 10-story building located in the Transitional Zone of Mexico City is designed, and a series of static and dynamic nonlinear analyses are carried out to evaluate its global structural properties and seismic performance. From the results of the nonlinear analysis, it is concluded that it is possible to construct tall confined masonry buildings in seismic zones. Actions that need to be undertaken in the short term to make this possible are identified.
