“…al [1], Özcan et. al [10], Hamid [3] and Marta Słowik and Tomasz Nowicki [11] used four points bending test rather than three points bending test in which the beam is longer than 1 m. However, Mujika [12] was found that the flexure modulus calculated on four points bending test without correction for both test methods is overestimated. All the past researchers used full steel fibrous concrete beam as the test specimens.…”

ABSTRACT:The introduction of steel fibres in concrete beam has been proposed as flexural cracks inhibitor. This research was conducted focusing on simply supported beam to determine the crack propagations in flexure by varying the steel fibre content placement in the beam. The 25 kg/m 3 steel fibre was chosen. Seven sets of 150×250×1000mm concrete beams consists of three RC beams with full steel fibrous concrete (SFRC), three RC beams with steel fibre placed within tension zone of the beam, three RC beams with steel fibre placed at the half of beam's tension zone, two conventional RC beams as control sample, one unreinforced concrete beam with full steel fibre, one unreinforced concrete beam with steel fibre at tension zone only and one unreinforced concrete beam with steel fibre at half of tension zone. The addition of steel fibre in the conventional RC beam showed that it inhibits the flexural cracks.

“…For fibre-reinforced cementitious composites, non-metallic fibres such as synthetic fibres were used to mainly develop high ductile characteristics after cracking, with no improvement of strength, known as engineered cementitious composites (ECC) or strain-hardening cementitious composites (SHCC) (Fischer and Li 2003;Lee et al 2012;Choi et al 2014;Cho et al 2012;Kim et al 2014). On the other hand, steel fibres are often used to mix in concrete or cementitious composites to refine their brittle characteristics by enhancing tensile and shear strength (Narayanan and Darwish 1987;Ashour et al 1992;De Hanai and Holanda 2008;Ö zgür and Khaled 2009;Ö zcan et al 2009;Lim and Hong 2016;Lu et al 2016).…”

Amorphous micro-steel (AMS) fibre made by cooling of liquid pig iron is flexible, light and durable to corrosion, then to be compatible with high flowable and disperable states of mixing as well as high ductile post-cracked performances to apply in fibre-reinforced cementitious composites. In the current research, AMS fibre-reinforced cementitious composites based on cement and alkali-activated ground granulated blast furnace slag mortars were newly manufactured and evaluated for the strength and ductile characteristics mainly by direct tensile and shear transfer tests in the variation in the volume of AMS fibres with two different lengths of 15.0 and 30.0 mm. As a result, it was found that 1.0-1.25% fibre volume fractions were recommendable for AMS fibre-reinforced cementitious composites to maximize direct tensile strength, ductile tensile strain, and shear strength of the composites. However, a further fraction of AMS fibre lowered these mechanical characteristics. Simultaneously, it could be said that AMS fibre-reinforced cementitious composites exhibited up to about 3.7 times higher in direct tensile strength and up to 2.3 times higher in shear strength, compared to AMS fibre-free specimens.

“…Reinforced HSC members required not only experimental testing, but also finite element modelling of the failure behaviour. Few researchers studied the finite element modelling of reinforced concrete beams [9][10][11] by using the ANSYS finite element package. However, the available publications on the finite element investigation of reinforced high-strength concrete beams are still limited.…”

Abstract. Development of technologies of high-strength concrete (HSC) beams production, with the aim of creating a secure and durable material, is closely linked with the numerical models of real objects. The three-dimensional nonlinear finite element models of reinforced high-strength concrete beams with a complex geometry has been investigated in this study. The numerical analysis is performed using the ANSYS finite element package. The arc-length (A-L) parameters and the adaptive descent (AD) parameters are used with Newton-Raphson method to trace the complete load-deflection curves. Experimental and finite element modelling results are compared graphically and numerically. Comparison of these results indicates the correctness of failure criteria assumed for the high-strength concrete and the steel reinforcement. The results of numerical simulation are sensitive to the modulus of elasticity and the shear transfer coefficient for an open crack assigned to high-strength concrete. The full nonlinear load-deflection curves at mid-span of the beams, the development of strain in compressive concrete and the development of strain in tensile bar are in good agreement with the experimental results. Numerical results for smeared crack patterns are qualitatively agreeable as to the location, direction, and distribution with the test data. The model was capable of predicting the introduction and propagation of flexural and diagonal cracks. It was concluded that the finite element model captured successfully the inelastic flexural behaviour of the beams to failure.
