“…Diagnostic load tests (Farhey, 2005;Jauregui, Licon-Lozano, & Kulkarni, 2010;Moses, Lebet, & Bez, 1994;Olaszek, Lagoda, & Ramon Casas, 2014;Russo, Wipf, & Klaiber, 2000) use a low load and verify if the stiffness and behaviour of the bridge is as expected. Several countries, such as Italy (Veneziano, Galeota, & Giammatteo, 1984), Switzerland (Bruehwiler, Vogel, Lang, & Luechinger, 2012) and France (Cochet et al, 2004b) require a diagnostic load test upon opening of a bridge.…”

Proof load tests (Cai & Shahawy, 2003;Casas & Gómez, 2013;Moses et al, 1994;Saraf, Sokolik, & Nowak, 1996) use a higher load and proof a certain capacity of a bridge. Ideally, this capacity can be linked to a probability of failure of the bridge, so that the result of the test and analysis is an estimate of the safety.…”

“…Diagnostic proof loading (Russo et al, 2000, Olaszek et al, 2014, Moses et al, 1994, Jauregui et al, 2010, Farhey, 2005 can be used on newly opened bridges to verify the stiffness as well as on existing bridges.

“…Proof loading (Saraf et al, 1996, Moses et al, 1994, Casas and Gómez, 2013, Cai and Shahawy, 2003 is typically carried out on existing brides. The result of a proof load test is a better understanding of the behavior of the bridge, which can be used as input for a probabilistic analysis (Lin and Nowak, 1984, Fu and Tang, 1995, Nowak and Tharmabala, 1988, Hall and Tsai, 1989, Rackwitz and Schrupp, 1985.…”

“…Among the countless approaches for assessing existing structures, field-testing has shown to be of significant importance. In particular, applications of field-testing to the structural assessment of bridges have shown that this technique can yield significant improvements in the understanding of actual structural behavior and, has therefore, become a generally accepted practice [7,64,75]. This methodology usually consists in capturing the structural response through the measured output of sensors while applying a controlled load that, for the case of bridges, is usually done using a test vehicle with known axle loads.…”

Este exemplar foi revisado e corrigido em relação à versão original, sob responsabilidade única do autor e com a anuência de seu orientador. The never ending support of my parents was also essential during this stage and without it nothing could have been accomplished.Special thanks goes to my brother for his free consultations and friendship during these not so easy years.I'd also like to thank my colleagues and friends from the University of São Paulo who endured the hard days of field work and helped in keeping me sane with a couple of beers after each job. A special mention must be made to Alfredo for his endless patience and wise words.To the friends, colleagues, and many housemates from Bethlehem. Who welcomed me into their lives and made the long periods away from home pass by so fast. A probabilistic life-cycle prediction model based on sectional analysis is proposed for reinforced concrete structures. The updating of the model parameters is done using a Bayesian updating approach in which the problem is defined as a reliability one. An algorithm that uses subset simulation is used to sample points from the updated parameter distributions. Testing data from a reinforced concrete railway bridge is used to demonstrate the methodology and its results.The description of a SHM system that was installed in the Jaguari River Bridge is also presented. During the stages of preparation for the installation of this system the bridge was inspected, had NDT performed, and field testing was conducted using a test truck. The results of these tests are also presented.Analysis of the collected data from the live-load response of the Jaguari River Bridge is used to demonstrate methodologies for obtaining live-load response distributions from monitoring data. The use of this live-load response data is also used for the life-cycle analysis of one of the bridge's cross-sections.Keywords: structural testing; structural health monitoring; reinforced concrete; bridges; life-cycle. 5 ResumoEste trabalho apresenta metodologias de integração de ensaios estruturais e Structural Health Monitoring (SHM) para a avaliação de pontes de concreto armado. O SHM diz respeito a um conjunto de praticas com o objetivo de acompanhar o comportamento estrutural através de sensores com o objetivo de acompanhar o comportamento da estrutura e determinar ações de manutenção de maneira proativa. As metodologias são apresentadas através do uso de dados coletados durante ensaios de pontes ferroviárias em concreto armado e do monitoramento continuo de uma ponte rodoviária.Um modelo para o ciclo de vida de estruturas de concreto armado baseado no método das lamelas é proposto. Os parâmetros deste modelo, que são considerados de maneira probabilística, são atualizados através de um método Bayesiano. Dados de ensaios de uma ponte ferroviária são utilizados nesta analise.A descrição de um sistema de monitoramento contínuo instalado na Ponte do Rio Jaguari também é feita. Durante as etapas de desenvolvimento do sistema a ponte foi inspecionada, ensaios não de...
