TL;DRAbstract

It presents in this paper study the influence of masonry provided with openings in the structural behavior of a reinforced concrete building of 27 floors.In finite element analysis computer program SAP 2000 by the masonry panels are replaced by equivalent diagonal struts.Also modeled in a finite element structure consisting of two columns and two beams filled with masonry.Finite element type shells were used in the modeling of masonry and springs were inserted at the interface.Was observed in this model the formation of the compression strut, which compares the width of the strut with experimental and analytical studies in the literature.The frames when interconnected with the masonry panels and subjected to horizontal actions such as winds and earthquakes transfer these efforts through a strut that is formed on the panel of masonry and structural changes the behavior of the building.The results show that masonry contributes to the overall stiffness of the building.These results are pr
