RESUMO:

A problem involving structural masonry refers to the impossibility of reforms. Partial or total removal of structural masonry walls may result in cracking, excessive spans or even progressive collapse of the structure. However, there are few studies about the behavior of structural masonry, in terms of stress redistribution, through inadvertent structural wall removals, as well as the possible progressive collapse associate with these situations, especially in structural masonry buildings above concrete floor structure. Thus, it becomes evident the importance of more studies about this topic. This research aimed to evaluate the stress redistribution and their implications in other elements of the structure, such as reinforced concrete masonry lintels, as well as to evaluate the influence of the concrete floor structure in this redistribution, indicating the verifications to be made for the progressive collapse study in these structures. For this, two buildings were modeled in SAP2000® commercial software using the equivalent frame model. The stresses were evaluated at the base walls and at vertical cross sections, in addition to the normal forces in the lintels, on near floors to the occurrence of removal walls caused by supposed inadvertent reforms. The results showed that: the stresses dissipate considerably along the floors from which the removals are considered; the masonry lintels have an important function in the stress redistribution, among other conclusions.
