The work presents results from numerical analyses performed in a 32-storey reinforced concrete building in Recife. Numerical finite element analyses were performed taking into account the modeling of reinforced concrete members only as well as the masonry infill panels, considered as equivalent diagonal struts. It was also analyzed a more refined model consisting of isolated infill masonry panels subjected to frame loading from 3-D finite element analyses. Support reaction, stress resultants and displacements on the top of the buildings, obtained from performed analyses, were compared. An increase in building stiffness was observed as well as stress resultant redistribution. Infill masonry panel stresses were also investigated in order to find out the places where it is most stressed
