Hofmann, Giane Alfenas Antunes (2019) Parameters for the prevention of pathologies in steel-structured buildings. PhD thesis, Universidade Federal de Ouro Preto, Brazil.
Abstract
Structured steel construction is an interesting option for the already established concrete structure in the Brazilian scenario, especially at a time when civil construction in Brazil is looking for more competitiveness and technology as a way to face the economic crisis in a market in great and constant change. However, for historical and cultural reasons, steel is still little used as a structural element in construction in Brazil. In order to promote the use of such material, it is necessary to have greater control over its characteristics, advantages and, especially, its possible pathologies. And the prevention of pathologies can avoid degradation, costs and even the collapse of the structure. In this work, essential parameters are defined in the prevention of pathologies related to steel the steel/closure in structured steel buildings interface. The identification of pathologies is done in five medium and large structured steel buildings. In possession of the information about the pathologies, the causative elements and the risk analysis of pathologies are surveyed through the tools of Total Quality Management, using, especially, the Ishikawa Diagram and the GUT Matrix. The results obtained show in which stage of the construction process should be applied parameters to prevent the pathologies found: corrosion in the structure, cracks in the closures, infiltrations in the interface closure / structure, leakage in the slabs between floors and transmission of sound by slabs and electrical installations.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
