000020148 520__ $$2eng$$aIn Peru, confined masonry (CM) walls are widely used as structural elements in low- and mid-rise dwellings in order to resist the gravity and seismic loads. To evaluate the seismic capacity, test results of four full-scale specimens subjected to cyclic load are presented and analyzed. The specimens were constructed with solid handmade clay bricks and lime mortar. The dimensions of all the specimens were kept constant while the reinforcement ratio of the bond beam and tie-columns were changed. The structural behaviors of the specimens were studied in terms of strength, lateral stiffness, dissipated energy, and equivalent viscous damping. Then, a macro-model based on an equivalent strut approach that considers a smooth hysteretic model was calibrated and validated in order to reproduce the behaviors of some specimens. The genetic algorithm (GA) that considered the experimental results was employed to develop the numerical model. The parameters obtained from the calibration process were applied to the other CM walls to evaluate their applicability. The results obtained from the numerical simulations and the experiments showed good agreements. The calibrated model can be used to assess the seismic behaviors and estimate damage to existing structures.
