Ecuador is home to numerous heritage structures constructed from fragile, earth-based materials, notably adobe. Recent seismic activities have exposed the inadequate performance of these buildings, attributed to their significant mass and limited seismic resistance. This article delves into the assessment of the old building of Simon Bolívar high school, highlighting various reinforcement methodologies for this adobe wall system featuring plan irregularities, situated in downtown Quito. The study posits that external forces apply in the direction of the wall's most robust plane, and such adobe walls exhibit limited resilience to in-plane lateral loads. A sensitivity analysis of the finite element discretization is showcased, leveraging a commercial software. This analysis determines empirical values connecting the proportion of the finite element to the wall's primary length. Consequently, this finite element meshing proposal aims to discern initial ratios for element size, facilitating an introductory calibration analysis centered on stress and displacement regulation. The paper scrutinizes the finite element meshing typically employed in two-dimensional structures, underscoring the critical nature of the meshing's initial calibration to yield dependable outcom.
