This work presents a case study on pathological manifestations characterized by cracks with wide widths, occurring with significant incidences and intensities in the superstructure of reinforced concrete, as well as in the walls of the building of the Audience of the Center of Education of the Federal University of Saint Maria, University Campus, Saint Maria, RS. In the development of this research the manifestations are analyzed in its symptoms, mechanisms, causes, origins and consequences, resulting in the achieving of a diagnosis for the problem. From this diagnosis suggestions are proposed for applicable therapeutically solutions. For verifications of the states service limits, evaluating the intensities of the deformations and the solicitant efforts that may act in the structural elements of the construction and, by consequence, in its walls, the superstructure of reinforced concrete was analyzed by finite elements. For this purpose the computational program SAP2000 Advanced 11.0.02 is used, considering compatible load situations with the use of the construction, emphasizing the actions of origin in the thermal variations. A diagnosis based on the comparative interaction between the achieved results and the incident pathologies was obtained. The analysis results for finite elements meet inserted to the body of this work, serving as mathematical parameters of good precision in the determination of the operating mechanisms, as well as in the evaluations of the origins and pertinent causes.
