Contribuição para a metodologia de inspecção de cabos de pontes suportadas por cabos com vista à sua manutenção

Abstract

This paper is dedicated to the study of all aspects relevant to the efficient inspection of the cable system of cable-stayed bridges. It begins with a general approach to cable-stayed bridges, highlighting their cable system and its particularities. Each one is characterized, with illustrative examples. Chapter 3 defines the main properties, requirements and tests of the materials used in the cable system, based on American and European standards. Chapter 4 devotes space to studying the fundamentals of cable-stayed bridge inspections. It looks at the qualifications of inspectors and their technical assistants, their responsibilities and duties, inspection planning, inspection equipment, access methods and safety practices. Chapter 5 deals with the inspection of cables in cable-stayed bridges, highlighting the types of inspection, their frequency and the inspection procedures to be adopted for each element of the cable system.Finally, Chapter 6 presents the conclusions and future developments, based on the analysis and response to the problem, the starting questions, the hypotheses and the objectives presented at the beginning of the work. The same chapter mentions the proposed inspection guide for cable-stayed bridge systems, which is essentially the main aim of this work. This guide was developed with the intention of helping any civil engineer and mid-level professional with the process of inspecting cable-stayed bridge cable systems, from the preliminary site visit, office activities to on-site activities (TRADUÇÃO NOSSA)
