The objective of this work is to evaluate the current situation of the concrete structure ofCentral Institute of Sciences (ICC), the larger and older construction of Brasilia University(UnB) Campus, with 720m of length, architectural project by Oscar Niemeyer andstructural design by the office of the engineer Sergio Marques de Souza. The study wasdeveloped with the characterization of the structure based on technical documents andstatement of people directly or indirectly connected to its conception and execution. Theresearch allowed a partial recovery of the building history, emphasizing the most importantaspects: construction beginning and conclusion, structural and architectural projects,technical responsibility and general details of construction. The work is part of the researchon ?Pathology, Maintenance and Repair of Structures? of the PECC/UnB, aiming toproduce a set of documents that contribute for the history of the structural engineering ofBrasilia.On the basis of an inspection program from the GDE/UnB method for damageclassification and assessment of concrete structures, this work proposed alterations in someof its procedures and elaborated a diagnosis of the physical situation of part of the ICCstructure, showing its main damage manifestations.An analysis of the roof structure of ICC was made with computational program SAP/2000to verify the influence of temperature variations, caused by beams length and nature of thesupports. Results shown that, even removing the transversal metallic elements that jointhese beams significant displacements still occurs in the structure , caused by the?platibandas? that compose the façade. On the basis of displacements and forces calculatedat the supports, new neoprene devices were designed for beam-column connections, whichcan contribute to correct the displacements problem mentioned.With research results indicating a ?severe? deterioration level for part of the structureexamined, a maximum period of six months for the proposed interventions was suggested,aiming to assure building serviceability and security.
