“…It was noticed that the load was carried primarily by the concrete matrix before cracks occurred for D i = 400 mm pipe, while the load was carried primarily by the steel wire cage for D i = 600 mm pipe in TEBT. For D i = 400 mm pipe, the finding of concrete matrix playing the most critical role to the F cr was identical to the observations reported in many previous studies . On the other hand, the increasing d w increases the F cr , while the other factors (at any level) have no significant influences on the F cr for D i = 600 mm pipe.…”

The inconsistency of orders of effective factors between D i = 400 mm pipe and D i = 600 mm pipe was considered due to the complexities of different combinations of pipe diameter, pipe wall thickness, pipe lengths, and other properties, such as reinforcements.…”

Materials include steel rebar, 7-9 steel wire, 5 glass fibers, 10 plastic fibers, 2 jute fibers, 11 steel fibers, 8,9,[12][13][14][15] and steel fibers combined with polypropylene fibers 16 have been widely applied in pipe reinforcement design, with a single type of material or a combination of these. Among these, pipes with fibers reinforced concrete instead of regular concrete alone with steel reinforcement have attracted the attention of the pipe manufacturing industry and carried out for practical purposes in past decades.…”

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.

An experimental program consisting in producing and testing reinforced concrete pipes (RCPs) under the three‐edge bearing tests considering different types of reinforcement was carried out. Four types of RCPs were produced, these reinforced with: (1) polypropylene macrofibers; (2) basalt microfibers; (3) combination of both (hybrid reinforcement); and (4) plain concrete. The analysis of the crack patterns and both service and ultimate mechanical responses allowed concluding that the use of fibers do not lead to an effective increase of the first cracking load; however, both types of fibers allowed a better crack width control respect to the standard RCP. In this regard, basalt microfiber reinforced concrete led to a better response caused by concentrated loads (jacketing) whilst polypropylene macrofibers increased the concrete pipe performance in terms of bearing capacity and flexural crack control. The hybrid fiber reinforced concrete was found to be the most suitable alternative for increasing the load bearing capacity and the crack width control for service loads. These incipient experimental results permit to conclude that this type of hybrid basalt‐polypropylene fiber reinforced concretes are an interesting alternative to traditional steel‐cage RCPs.
