The steel structure, together with conventional closing systems, does not always present the expected performance, as the solutions for the bonding between these two elements are not always adequate and can result in pathologies in buildings. In this context, the objective of this work was to analyze pathological manifestations in a steel-structured building with a ceramic brick masonry closing system. For this purpose, inspections were carried out in the building, which is in use, to identify existing degradations in the structure's interfaces with the closure, as well as the causes of the damage observed, and proposals were made to correct and prevent them. It was possible to verify that the adoption of construction techniques and elements was inadequate, due to the lack of details, specifications and compatibility in projects, and also periodic maintenance, which resulted in the appearance of pathological manifestations throughout the entire building. Solutions and constructive techniques aimed at correcting the damage and preventing the appearance of new pathological manifestations were presented. The analysis indicated that, however, a treatment of the pathologies should be carried out, as they are phenomena in constant advancement and that the pathologies identified in the building are subject to recovery.
