“…It can be concluded that the finite element model predictions agree reasonably with the experimental data obtained in the authors' previous work [31] and that reported by de Figueiredo et al [19,20]. Furthermore, the observed error, in most cases, fell on the conservative side of the experimental results.…”

“…The experimental program was described in more detail elsewhere [31]; however, it is briefly outlined herein for the sake of completeness. SFRC pipes were cast at an industrial precast concrete plant in Oakville, Ontario, which uses the dry-cast production method.…”

“…[3,16,18,24,28,30,31]) investigated the mechanical performance of precast SFRC pipes. Several parameters were explored, including the pipe internal diameter (D i ), wall thickness (h), fibre content (W f ), fibre type, and the targeted pipe ultimate strength.…”

“…The present study aims at developing a 3D finite element model simulating the three-edge-bearing test of SFRC pipes. The model was validated using experimental data generated previously by the authors [31], as well as other experimental results available in the open literature. Consequently, the validated model was used to conduct a parametric study capturing the following parameters: pipe diameter, pipe wall thickness, and fibre type and content.…”

“…Estudos anteriores têm investigado aspectos do comportamento mecânico, durabilidade e viabilidade técnica do tubo de concreto reforçado com fibras de aço (por exemplo, Figueiredo et al (2007), de la Fuente et al (2011), Mohsen (2014), e Mohamed (2015)). No entanto, entre as dificuldades de aplicação do tubo de concreto de armadura descontínua com fibras de aço tem-se as restrições de recomendações normativas e código de projeto estrutural.…”

Resumo Os tubos de concreto com fibras de aço apresentam-se como uma variante tecnológica interessante. No estudo incipiente na localidade, o objetivo principal é o de avaliar a viabilidade técnica de tubo de concreto de armadura descontínua com fibras de aço orientadas aleatoriamente, mediante o ensaio de compressão diametral para análise do comportamento mecânico. O objetivo secundário é o de verificar a absorção de água e o teor efetivo de fibras na ponta, no meio e na bolsa do tubo. No estudo utilizaram-se as fibras de aço DRAMIX 80/60 ou 65/35, soltas ou coladas em pente, nos teores teóricos de 0,25%, 0,38% e 0,50%. Os resultados apontaram que apenas os tubos de concreto da série TCFA 80/60 - FCP nos teores efetivos de fibras de 0,36% e 0,50% e em todos os teores efetivos da série TCFA 80/60 - FS atingiram a mínima carga de ruptura e pós-fissuração estabelecida pela NBR 8890 (ABNT, 2007). Os resultados de absorção de água ficaram abaixo da máxima absorção recomendada pela NBR 8890 (ABNT, 2007) e houve maiores níveis de absorção e de teor efetivo de fibras na cadeia da ordem ponta, meio e bolsa. Ao final, mostrou-se oportuna a viabilidade técnica de tubo de concreto com fibras de aço na localidade.

By utilizing Taguchi method, this paper presents a simplified approach that aims at developing technical recommendations of control factors of reinforcement and concrete for steel wire reinforced concrete pipes (SWRCP). For this purpose, the structural behaviors of full scale of 400 and 600 mm inside diameter SWRCPs were analyzed. Three control factors, namely wire diameter (dw), wire winding pitch (pw), and water/cement ratio of concrete (w/c of concrete) were designed in an L9 orthogonal array. The best possible levels were determined for maximization of crushing load (Fcr) and ultimate load (Fu) in three‐edge bearing tests and minimization of crack width (Wcr). Based on the results, the economical and optimal control factors of dw, pw, and w/c of concrete for SWRCPs with inside diameter of 400 mm are 6.5 mm, 100 mm, and 33.5%, respectively. For SWRCPs with inside diameter of 600 mm, the optimal control factors of dw, pw, and w/c of concrete are 6.5 mm, 33 mm, and 33.5%, respectively. In addition, by the use of analysis of variance, the contribution percentages of control factors were obtained and were used as the most effective factors on the Fcr, Fu, and Wcr for SWRCPs. Through the implementation of the study, this paper concludes a practical and significant overall idea of designing SWRCPs for pipe manufacturing industry.
