Influence of the reinforcement corrosion on the bending moment capacity of reinforced concrete beams: a structural reliability approach

Abstract: Reinforced concrete structures are, certainly, one of the most used types of structure around world. When it is located in non-aggressive environments, it respects, in general, the structural life predicted. Unless the structure be used improperly. However, the durability of these structures is strongly connected to degradation processes whose origin is environmental and/or functional. Among these processes, it is worth to mention those related to corrosion of reinforcements. The reinforcement's corrosion is d… Show more

“…The lack of concrete cover thickness in reinforced concrete is one of the main failures in civil construction, and this is the main cause of the steel corrosion (Liberati et al, 2014;Medeiros et al, 2017;Silva Júnior et al, 2020). Besides that, other factors may be responsible for the appearance of these manifestations, such as the high porosity of the concrete matrix due to the high water-to-cement ratio and the presence of aggressive agents incorporated into the concrete matrix at the time of the structure's execution, with were already explained earlier.…”

“…Neste método, amostras de variáveis aleatórias são utilizadas para construir um conjunto de realizações do experimento com o intuito de descrever a falha, os espaços seguros, correlacionados à confiabilidade, e calcular a probabilidade do evento, conforme Equação (2). As formulações aqui descritas, foram resumidas de acordo com Liberati et al (2014).…”

“…Assim, mesmo sob a existência de diversos modelos representativos da corrosão [3,4,[12][13][14][15][16][17][18][19][20], as estimativas dos períodos de despassivação do aço ainda apresentam erros associados à falta de generalidade dos modelos no que diz respeito às condições de exposição e/ou aspectos climáticos do ambiente que circunda as estruturas de concreto [22]. Ademais, LIBERATI et al [22] e RAMEZANIANPOUR et al [23] relatam a falta de representação das incertezas presentes em parâmetros associados às condições climáticas do ambiente, sendo necessário, portanto, acrescentar variáveis aleatórias que descrevam a variabilidade destes parâmetros.…”
