This research showcases the results of the nonlinear static analysis of the different probable combinations for multi-family buildings in the Metropolitan District of Quito (DMQ). For this study, the four most recurring typologies within a sample of 11,556 structural units were identified. Special emphasis is placed on modeling the nonlinear-fragile behavior of masonry elements, both framed and unframed. From the analysis, a global nonlinear behavior of the structure is derived, approximating the real behavior represented by capacity curves. The various capacity curves of each theoretical model are subjected to two seismic scenarios (with return periods of 100 and 475 years), considering the seismic amplification due to soil types B-C as outlined in the NEC15. This analysis provides an initial glimpse into the replacement cost in the event of a collapse of the structures examined under the proposed seismic scenarios. These findings will be validated in the subsequent study titled "Fragility Curves, based on Spectral Scenarios applied to Structural Typologies of Quito-Ecuador, Project GEM-SARA.
