“…For FRC, the load drop is slighter than that of plain concrete owing to fiber crack-bridging effect, especially for SFRC and BFRC. Furthermore, a slower rate of elastic stiffness degradation is observed for SFRC specimens, which is consistent with the conclusions in the literature [34,37]. Figure 7 depicts a schematic diagram of a cyclic stressstrain curve extracted from the current results, which is believed to be well suited to reproduce the actual cyclic compressive response.…”

“…ose research outcomes have led to a great success in the prediction of concrete cyclic loading responses and serve as a base for the nonlinear analysis of concrete structural performance. In comparison with plain concrete, research studies on the cyclic mechanical behavior of FRC are rarely reported in the literature, with BFRC in particular [33][34][35][36][37][38]. Of the limited tests for FRC under cyclic loading, the study conducted by Otter and Naaman is worth quoting.…”

This paper investigates the cyclic stress-strain behavior of steel-polypropylene-blended fiber-reinforced concrete (BFRC) under uniaxial cyclic compression. A total of 48 prism specimens were tested for different fiber volume fractions and aspect ratios. The results show that the introduction of blended fibers has synergetic effects on improving the cyclic behavior of concrete in terms of peak strength, postpeak ductility, hysteretic energy dissipation, and stiffness degradation. Moreover, the increase in the volume fractions of both steel and polypropylene fibers can lead to a remarkable decrease in plastic strain accumulation. Furthermore, the stiffness degradation ratio as well as the stress deterioration ratio of BFRC can be significantly alleviated in comparison with those of plain concrete, notwithstanding that the degradation amount is insensitive to the variations of fiber parameters. Subsequently, based on the test results, a constitutive model is developed to generalize the cyclic stress-strain responses of BFRC, with the contributions of blended fibers taken into account. The developed model is then verified by independent experimental results and other test data reported in the literature. It is observed that the prediction yields a close estimation of the cyclic compressive behavior of BFRC with varying fiber parameters.

Recently, the multiscale hybrid fiber reinforced cementitious composites (MSHyFRCC) with steel fibers, polyvinyl alcohol (PVA) fibers, and calcium carbonate whiskers had developed with improved mechanical properties under static load. Although, there is still a research gap to study its behavior and properties under the action of earthquake load. In this work, the properties of steel fibers, PVA fibers, and calcium carbonate whisker hybrid FRCC are evaluated by using single degree of freedom hydraulic shaking table. A total of 10 mixes having different mix proportions, fiber lengths, and contents of steel fibers, PVA fibers, and calcium carbonate whiskers are considered. The stress–strain curves, failure mode of cubes, compressive strength, peak micro‐strain, strain energy density, failure mode of column specimen, displacement‐time curves, strain‐time curves, and top acceleration‐time curves are studied. The multiscale hybrid fibers offer resistances against crack growth under dynamic load which results in longer time period with improved displacement, strain, and acceleration. The 1.5% steel fibers of 13 mm, 0.75% PVA fibers of 6 mm with 1% calcium carbonate whiskers and 1.25% steel fibers of 35 mm, 0.55% PVA fibers of 12 mm with 2% calcium carbonate whiskers are proposed to be the optimized mixes for short‐ and long‐length hybrid fibers, respectively.

The focus of this study is to investigate the effect of using coarse recycled concrete aggregates (RCAs) as an alternative material to natural coarse aggregate on the fresh, mechanical and durability behavior of concrete reinforced with steel fiber. Eighteen unique concrete mixes with RCA content of 0%, 50%, and 100% and steel fiber content of 0%, 1%, and 2% were prepared, and tests were performed to study slump, density, compressive and splitting tensile strengths, flexural behavior, surface hardness, surface abrasion resistance, water absorption, and sorptivity of each mix. It is shown that concrete containing RCA has a lower unit weight, compressive, splitting tensile and flexural strength, flexural toughness, surface hardness, and abrasion resistance, and a higher water absorption and sorptivity in comparison with conventional concrete. An increased compressive, splitting tensile and flexural strength, flexural toughness, surface hardness, and abrasion resistance, and a decreased water absorption and sorptivity of concrete with an increased steel fiber content from 1% to 2% is less significant compared to those from 0% to 1%. The results also show that, at RCA content of 50%, incorporating 1% steel fiber develops a concrete mix with similar or even better properties compared to unreinforced conventional concrete. At 100% RCA content, incorporating 2% steel fiber develops a concrete mix with similar properties to unreinforced conventional concrete having water to cement ratio of 0.3, but inferior properties to unreinforced conventional concrete having water to cement ratio of 0.5. These findings indicate that recycled aggregate concrete with similar or even better properties compared to concrete with natural aggregate can be developed through properly designing mixes, providing a great avenue toward the production of green construction material for structural applications.
