Abstract
Structured steel construction is an interesting option to the already established concrete structure at a time
when Brazilian civil construction seeks more efficiency. Encouraging the use of this material requires a
better understanding of its characteristics and especially its possible pathologies to prevent degradation,
costs, and even structural collapse. This study uses Total Quality Management tools are applied to analyze
the pathologies present in five medium and large steel-structured buildings. The causative elements are
identified with the information about the buildings’ pathologies, and the risk analysis of the pathologies
is performed using, especially, the Ishikawa Diagram and the GUT Matrix. The most frequent pathologies
highlighted in the study are corrosion in the structure, cracks in the closures, and infiltrations in the
interface closure/structure. The main causes, according to the Ishikawa diagram and the GUT matrix,
are related to construction technique, labor, environmental conditions, and raw material used. The results
show that it is possible, through the tools of Quality Management, to establish the risk of each pathology
and its origin and determine the degree of risk that each one offers.
