CONCRETE SHEARE WALLS STRENGTHENING STRUCTURAL ELEMENTS FOR SEISMIC REHABILITATION OF MASONRY BUILDINGS

This paper aims at investigating the behavior of masonry buildings strengthened with concrete shear walls. To this end, a masonry wall with openings extracted from an individual two-storey masonry building is modeled using ANSYS finite element software. A number of nonlinear static analyses were conducted on the model. The nonlinear behavior of the existing model was compared with that of the model enhanced with concrete shear wall. The re sults obtained from the numerical analyses confirm that the load-carrying capacity of the unreinforced masonry buildings degrades due to the global failure of the wall. Whereas, the masonry buildings strengthened with concrete shear wall may achieve their target displacement. Moreover, the results reveal that the wall load-carrying capacity may be upgraded, if the added shear wall is connected to both the diaphragm and adjacent masonry wall.
