Abstract

Confined masonry walls are widely used in residential construction due to their low cost and good structural resistance. In this type of structure, shear stress is predominant, potentially leading to brittle failure characterized by the sudden formation of diagonal cracks that cross the masonry panel. This condition becomes more critical when the structure is subjected to lateral seismic loading. Masonry, steel, and concrete elements all experience significant degradation of their mechanical properties with increasing seismic energy. This paper presents a numerical study on the lateral response of a confined masonry wall subjected to lateral seismic excitation. A nonlinear 3D finite element computational model was developed using the commercial software ABAQUS. The model considers the material behavior through the calibration of a plastic damage model for confined masonry using experimental data from scientific literature. The results obtained are validated by comparison with numerical and experimental tests available in the literature and with current design code provisions.
