“…During the four-point bending test, the TRM beams eventually fractured as the dominant crack formed at the bottom center gradually propagated. When a beam fractures due to one dominant flexural crack, the flexural behavior can be briefly analyzed by idealizing the deformation and failure modes of the flexural member, as shown in Figure 9 [45][46][47]. From the failure mode shown in Figure 9, the relationship between compressive axial strain at the top of the section ( , c top ε…”

The flexural behavior of mortar beams reinforced with coated carbon-fiber textile was experimentally analyzed in this study. Accordingly, pull-out and bending tests were performed on textile-reinforced mortar (TRM) beam specimens. The experimental results demonstrated the superior bond performance of the coated carbon-fiber textile. The TRM beam exhibited sufficient ductility even after the occurrence of flexural cracks. In addition, a theoretical analysis method for predicting the flexural behavior of a TRM beam was established based on the experimentally determined bond behaviors of the textile reinforcement in cementitious materials. The analysis demonstrated that the bending behavior of the TRM beam was reasonably predicted. The results of this study can serve as basic data for the structural application of textile-reinforced cementitious composites.

“…When dealing with compressive behavior, a parabolic equation was used, as is commonly done with plain concrete [25] and with a conventional FRC [12,26,27]. On the other hand, although JSCE TC 334 [8] proposed a parabolic equation without a descending region, a linear relation has been also commonly used to describe the compressive behavior of HPFRCC.…”

“…Ostergaard et al [9] adapted a hinge model that includes tensile strain hardening and tension softening to predict the flexural behavior of the ECC. A section analysis method was also used for the analysis of convectional FRC [12] and ECC [13]. Recently, a meso-mechanical approach [14] has been developed to explicitly simulate the contribution of matrix and fibers and their mutual interaction.…”

Flexural Behavior of HPFRCC Members with Inhomogeneous Material Properties

et al. 2015

In this paper, the flexural behavior of High-performance Fiber-Reinforced Cementitious Composite (HPFRCC) has been investigated, especially focusing on the localization of cracks, which significantly governs the flexural behavior of HPFRCC members. From four points bending tests with HPFRCC members, it was observed that almost evenly distributed cracks formed gradually, followed by a localized crack that determined the failure of the members. In order to investigate the effect of a localized crack on the flexural behavior of HPFRCC members, an analytical procedure has been developed with the consideration of intrinsic inhomogeneous material properties of HPFRCC such as cracking and ultimate tensile strengths. From the comparison, while the predictions with homogeneous material properties overestimated flexural strength and ductility of HPFRCC members, it was found that the analysis results considering localization effect with inhomogeneous material properties showed good agreement with the test results, not only the flexural strength and ductility but also the crack widths. The test results and the developed analysis procedure presented in this paper can be usefully applied for the prediction of flexural behaviors of HPFRCC members by considering the effect of localized cracking behavior.

“…In the 1990s, the introduction of macro-synthetic bers (MSF) into the construction industry has seen vast research into the likelihood of using discrete bers to substitute light gauge steel grids and steel bers in rigid pavements, shotcretes, and structural concrete (Oh et al 2005;Suji et al 2007; Buratti et al 2011). Generally, synthetic bers have an elastic modulus usually in the range of 3-7 GPa, considerably lower compared to engineered steel bers with a modulus of elasticity of about 210 GPa, studies have shown that depending on the concentration and geometry, they substantially advance the toughness, ductility, spalling-resistance, and durability of plain concrete (Oh et al 2005(Oh et al , 2007; Kazmi et al 2018a). Contrary to steel bers, MSF offers numerous advantages, they are lightweight, insulating, corrosion-resistant, and economical.…”

Nylon waste bers (NWF) similar to new nylon bers possess high tensile strength and toughness, hence, they can be used as an eco-friendly discrete reinforcement in high-strength concrete (HSC). This study aimed to analyze the mechanical and permeability characteristics and life cycle impact of HSC with varying amounts of NWF and microsilica (MS). The results proved that NWF was highly bene cial to the tensile and exural strength of HSC. At the combined addition of 0.5% NWF and 7.5% MS, splitting-tensile and exural strength of HSC experienced net improvements of 49% and 55%, respectively. Lower doses of NWF were bene cial to the durability of HSC. However, 1% NWF was harmful to the durability of concrete. For the optimum mechanical performance of HSC, 0.5% NWF can be used with 7.5% MS. The use of MS also nulli ed the negative effect of the high volume of NWF on the penetration resistance of HSC.
