Towards the literature reports [1], quite a few bridges are suffering functionality degradation caused by the corrosion with the external steel strands. For instance, the Bickton Meadows Bridge and two other post-tensioned bridges inside the Uk collapsed due to corrosion in prestressing tendons [4]. Serious corrosion in prestressing tendons hasPublisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations.Copyright: 2021 by the authors.

Because of the corrosion-free property and higher tensile strength, this trouble is usually solved by utilizing fiber-reinforced polymer (FRP) tendons as a perfect alternative to steel strands with proper collision and fire protection [6]. On the other hand, the mechanical behavior of FRP is linear elastic up to failure, as well as the ductility on the beams mostly dependent around the compression plasticity of concrete, which lead to the brittle failure of FRP Histone Methyltransferase| prestressed concrete members [9]. The low ductility is amongst the crucial drawbacks limiting the widespread application of FRP-reinforced typical strength concrete structures. Therefore, based around the drastically higher strength and ultimate compressive strain of UHPC, the combined use of UHPC and FRP reinforcements is viewed as to become an effective method to enhance the ductility of your beams. Different studies reported on the structural performance of UHPC beams, and these studies mostly discussed the effect of fiber properties (i.e., fiber form, geometry, orientation and so on.), fiber content material and curing conditions on flexural behavior [105]. These research show that the higher strength of UHPC enhanced the flexural capacity of beams. The presence of steel fibers drastically improved the postcracking stiffness and cracking response. In unique, a higher fiber volume content material could lead to a higher flexural capacity, and an increase within the length of steel fibers along with the use of twisted steel fibers could improve the postcracking response and ductility. The room temperature cured beams showed much better ductility than the hot-cured beams. Further, quite a few researchers created analytical strategies to calculate the flexural capacity of UHPC beams. Shafieifar et al. [16] compared the accuracy of existing equations in different design recommendations for predicting the flexural capacity of UHPC beams. The outcomes indicated that American Concrete Institute (ACI) 318 [17] method for normal strength concrete tended to underestimate the ultimate capacity of UHPC beams. By contrast, ACI 544 [18] and Federal Highway Administration (FHWA) HIF-1 [19] solutions could predict the ultimate capacity with an acceptable accuracy. Additionally, distinctive types of FRP have been investigated as prestressed tendons in preceding studies [207]. For example, Ghallab and Beeby [25] evaluated quite a few design and style parameters could have effect around the ultimate stress in external steel tendons and aramid FRP (AFRP) tendons. The test benefits suggested that the non-prestressed reinforcement ratio and span to depth ratio slightly effected the ultimate strain of AFRP tendons, whereas the successful prestressi.
