Análisis experimental y analítico de las propiedades estructurales ante cargas laterales de una mampostería confinada y una mampostería reforzada

Abstract

This study focuses on the analysis of the structural properties of structural masonry walls. For this purpose, a confined masonry wall and reinforced masonry wall were tested by cyclic lateral load tests. From the hysteresis curves obtained from the cyclic lateral load tests, the maximum capacity, energy dissipation, equivalent viscous damping, secant stiffness, displacement ductility, and drifts were determined for each masonry wall. After the tests, the calibration of the capacity curves have been performed. For the Confined Masonry Wall, the SeismoStruct Software was used, which uses the double strut diagonal model for the analysis of infill panels. For the Reinforced Masonry Wall, a routine used in a previous study by the MSc Carlos Ayala in his master's thesis was used, for reinforced masonry walls, in the OpenSees Software. As a result of the comparisons between the properties of the masonry walls, it had that both masonry have good seismic behavior, but there are clear differences in ductility, initial stiffness, energy dissipation, drifts and construction costs.
