Book excerpt: Nowadays, civil structure still faces with the same problem of uncontrolled flexural strength that can make cracks occured on the beam surface and can reach to the reinforcement bar. How to come this problem is by adding some additive materials like steel fibres. Steel Fibre Reinforced Concrete (SFRC) can be produced by adding some amount of fibre in the concrete mix. The function of SRFC is to overcome the problem of the concrete that has the weakness about the strength. The SFRC will be function to improve or increase the strength of the concrete due to the increase of the loading. Steel Fibre Reinforced Concrete (SFRC) materials are very attractive for use in civil engineering applications due to their high strength-to-weight and stiffness-to-weight ratios, corrosion resistance, light weight and potentially high durability. For this study, the variable is the percentage of steel fibre. The percentage of steel fibre is 0.10%, 0.30%, 0.50%, 0.70% and 0.90%. All of this percentage is calculated in terms of volume. The objectives of this study are to find the significant of shear due to a variation of steel fibre ratios in beam design, to find out the value of compressive and bending stress of the samples and to compare and choose the optimum percentage of steel fibre contents in concrete structure respect to its shear strength. Concrete compression test and flexural test was conducted. The graphs used to present the results. Higher percent of steel fibre will give the higher value of shear, compressive and flexural.

This book was released on 2010 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steel Fibre Reinforced Concrete can be manufactured by adding steel fibre to a concrete mix design. Steel fibres were adding to the concrete in order to get more strength. The concrete grade of 30 N/mm2 was used during the preparation of the concrete mixture for the usage of normal concrete as the control sample and sample with 0.15%, 0.25%, 0.35%, 0.45% and 0.55% of steel fibre in terms of volume. Compression test and flexural test was implemented which was accordance to the ASTM C-39 and ASTM C-78 respectively. Compression test were tested to cube and flexural test were tested to beam sample. The graphs were used to present the result. Shear strength became increased due to the percentages of the steel fibre. If the percentages of steel fibres were high, the shear strength was also high. The highest value of shear strength, 14.47kN is for 0.55 % which is the highest value of steel fibre reinforcement in this study. With mix of concrete design with percentage of steel fibre reinforcement in term of volume, optimum compressive strength for 7 days of curing at 20.07 N/mm2 can be achieved at 0.55% of steel fibre reinforcement. Meanwhile, optimum compressive strength for 28 days of curing at 29.31 N/mm2 can be achieved at 0.15% of steel fibre reinforcement. From this study, the usage of steel fiber in concrete will increase the shear strength of the concrete. That's mean, steel fibre can be use for reduce shear reinforcement in concrete.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a systematic approach to the experimental, theoretical, and numerical investigation of reinforced concrete (RC) T-beams strengthened in shear with glass-fibre-reinforced polymers (GFRP) with variation in transverse steel reinforcements. It discusses experiments conducted on simply supported RC T-beams for control beams with and without transverse steel reinforcements and beams strengthened in shear with GFRP sheets and strips in different configurations, orientations, and variation of layers for each type of stirrup spacing. The book also includes a detailed numerical study using ANSYS performed in two stages. The first stage consists of selecting and testing relevant materials in the laboratory to establish the physical and mechanical properties of the materials. The second stage then involves testing beams for shear under two-point static loading systems. The test results demonstrate the advantage of using an externally applied, epoxy-bonded GFRP sheets and strips to increase the shear capacity of the beams. The finite element method (FEM) analysis results verify the experimental results. The book will serve as a valuable resource for researchers and practicing civil engineers alike.

Book excerpt: This book sheds light on the shear behavior of Fiber Reinforced Concrete (FRC) elements, presenting a thorough analysis of the most important studies in the field and highlighting their shortcomings and issues that have been neglected to date. Instead of proposing a new formula, which would add to an already long list, it instead focuses on existing design codes. Based on a comparison of experimental tests, it provides a thorough analysis of these codes, describing both their reliability and weaknesses. Among other issues, the book addresses the influence of flange size on shear, and the possible inclusion of the flange factor in design formulas. Moreover, it reports in detail on tests performed on beams made of concrete of different compressive strengths, and on fiber reinforcements to study the influence on shear, including size effects. Lastly, the book presents a thorough analysis of FRC hollow core slabs. In fact, although this is an area of great interest in the current research landscape, it remains largely unexplored due to the difficulties encountered in attempting to fit transverse reinforcement in these elements.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The ACI 318-08 building code allows to use the steel fiber reinforcement as alternative shear reinforcement with satisfying certain criteria when a beam is required minimum shear reinforcement. However, this provision applies to a nonprestressed and prestressed concrete beam such that it could be conservative since the shear strength of prestressed concrete beam is generally enhanced due to the prestressing force. This is due partially to the fact that the provision has been accepted based on researches, mostly conducted in nonprestressed concrete beam. Most of experiments conducted for prestressed concrete beam in small scale tests, with a height of specimens were less than 10 in. A larger scale of experiment is required due to concerns of size effect. In addition, in order to evaluate the qualification of a Steel Fiber Reinforced Concrete (SFRC) mixture used for structural applications, such as increasing shear resistance, a material evaluation method is essential. Currently ASTM or ACI Committee 544 (Fiber-Reinforced Concrete) does not recommend any standardized test method for evaluating shear performance of a particular SFRC material. This study addresses the research gaps described above by testing large-scale Steel Fiber Reinforced Prestressed Concrete (SFRPC) beams as well as developing a simple laboratory test techniques. A total 13 simply-supported beams for large-scale test with a shear span to effective depth ratio of 3.0 and a height of 24 in. were subjected to monotonically-increased, concentrated load. The test parameters were mainly included compressive strength, volume fraction of steel fibers, compressive reinforcement ratio. The results of large-scale test showed that the use of hooked steel fibers in a volume fraction greater than or equal to 0.50% volume fraction of steel fibers (67 lb per cubic yard), which is less than requirement by ACI 318-08 (0.75%, 100 lb per cubic yard), led to substantial enhancement of shear behaviors including the first cracking, the ultimate, and ductility. High compressive strength of SFRC, greater than 9000 psi, which is higher than ACI 318-08 requirement (less than 6000 psi) could be used as well. However, there was no significant effect from compressive reinforcement ratio. A simply shear test method for SFRC was proposed in this study. The test apparatus is almost exactly the same as the conventional ASTM bending test with only minor modification, in addition, it could simulate a pure shear stress by adjusting loading and support positions. By introducing a proper reinforcement for bending stress, it was possible to evaluate shear performance of SFRC with clear and uncomplicated shear stress field in the critical section.

This book was released on 2019 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research study consists of two separate phases. In the first phase, an experimental study was conducted to identify the shear-enhancement and failure mechanisms behind the ultimate shear strength of steel fiber-reinforced concrete (SFRC) slender beams by utilizing the full field deformation measuring capability of digital image correlation (DIC) technology. A total of 12 large-scale simply supported SFRC and RC beams with a range of heights including 12 in. (305 mm), 18 in. (457 mm), 24 in. (610 mm),36 in. (915 mm), and 48 in. (1220 mm) were tested under monotonic point load. The greater shear strength in SFRC beams stems from the fiber bridging effect which delays the propagation of the cracks into the compression zone. In contrast to the traditional assumption for either plain concrete or SFRC beams, where the shear contribution resulting from dowel action is completely neglected, this research clearly shows that the dowel action has an appreciable effect on the ultimate shear strength. Its contribution varies from 10% to 30% as the beam depth increases from 12 in. (305 mm) to 48 in. (1220 mm). On the other hand, the compression zone's contribution decreases from 69% to 36%with the increase in beam depth. In addition, the shear contribution from the fiber bridging effect along the critical shear crack stays virtually unchanged at 20%, regardless of beam depth. In this study, the minimum shear strength obtained was in the range of 5 SQRT (f'c) psi (0.42 SQRT (f'c) MPa) for the beams with the greatest depth. This indicates that the maximum allowed shear stress limit of 1.5 SQRT (f'c) psi (0.125 SQRT (f'c) MPa) specified in ACI 318-14 is on the very conservative side. While the size effect on ultimate shear strength of plain concrete beams has been well researched in the past decades, limited tests were carried out to study the extent and mechanism of size effect in steel fiber-reinforced concrete (SFRC) beams. Current American Concrete Institute's ACI 318 Building Code restricts the use of steel fiber as minimum shear reinforcement to beams with a height up to 24 in. (610 mm). In the next phase of the study, in addition to the analyzing of the current testing data, the laboratory test results from the first part of the study and the respective digital image correlation (DIC) images were examined to identify the underlying factors that cause size effect on ultimate shear stress of SFRC slender beams. Moderate size effect was observed in the beams tested in this study. Through the full field strains and a mechanical based analysis, it was found that the size effect is a function of both the beam height and the shear span length.In larger beams, due to the greater horizontal and vertical distance from the compression zone to the supports, the critical diagonal shear crack was able to propagate deeply into the top of the beams. As a consequence, the compression zone exhibits less contribution to shear resistance in larger size beams, and the dowel action becomes more critical. Therefore, a minor flaw in dowel zone such as lacking well-distribution of steel fibers results in early destruction of dowel resistance and shear failure.

Book excerpt: fib Bulletin 57 is a collection of contributions from a workshop on "Recent developments on shear and punching shear in RC and FRC elements", held in Salò, Italy, in October 2010. Shear is one of a few areas of research into fundamentals of the behaviour of concrete structures where contention remains amongst researchers. There is a continuing debate between researchers from a structures perspective and those from a materials or fracture mechanics perspective about the mechanisms that enable the force flow through a concrete member and across cracks. In 2009, a Working Group was formed within fib Task Group 4.2 "Ultimate Limit State Models" to harmonise different ideas about design procedures for shear and punching. An important outcome of this work was the ensuing discussions between experts and practitioners regarding the shear and punching provisions of the draft fib Model Code, which led to the organization of the Salò workshop. Invited experts in the field of shear and FRC gave 18 lectures at the workshop that was attended by 72 participants from 12 countries in 3 different continents. The contributions from this conference as compiled in this bulletin are believed to represent the best of the current state of knowledge. They certainly are of general interest to fib members and especially helpful in the finalization of the 2010 fibModel Code. It is hoped that this publication will stimulate further research in the field, to refine and harmonize the available analytical models and tools for shear and punching design.

Book excerpt: The main objective of this investigation was to determine the influence of adding two different shapes with different lengths of steel fibres on the shear behaviour of lightweight and normal weight concrete beams with normal and high concrete grades. Thirty-six prisms of (100 mm wide, 100 mm deep, and 400 mm long) and seventy two cylindrical samples of (100 mm diameter  200 mm high) were cast and tested to determine the concrete mechanical properties for specimens. These samples were tested in order to discover the role of steel fibres on enhancing concrete properties in general. The modulus of rupture, flexural toughness, toughness, compressive strength and splitting tensile strength were inspected based on the small-scaled material samples. In the structural experiment, a group of twelve large-scaled reinforced concrete beams without shear reinforcement were primarily analyzed, designed and tested in the structures lab at Memorial University of Newfoundland (MUN). These specimens were built to study the load-deflection curves, shear and flexural behaviour, concrete and steel strains and the ultimate load resistance. Simply supported beams with dimensions of (200 mm wide, 400 deep, and 2900 mm long) were structurally tested, analyzed and discussed. in order to investigate the previous responses. Three factors were proposed in this experiment. The first factor was the type of the aggregates and the second parameter taken into consideration was the concrete compressive strength that divided the beams into two groups of high and normal strengths. Thirdly, two different lengths of steel fibres with different end-shapes were considered as the third variable in order to evaluate the effects of the length of the steel fibres on the shear behaviour. All beams contained 1.46% of longitudinal tension reinforcement ratio. Besides this, a fixed concrete cross section was suggested for all beams. Testing specimens were setup on a specified constant shear span-to-depth ratio of 3. According to a recommendation by ACI, a fixed volume fraction of 0.75% of steel fibres was added to SFRC beams. The specimens with long fibres resisted higher shear stresses and were more ductile than the ones reinforced with shorter fibres. Overall, the presence of both short and long steel fibres improved beams shear resistance by a range varied from 35% to 72% compared to reference RC beams. However, shear strength of beams with long steel fibres enhanced more by an average amount of 10% in contrast with short SFs beams.

Available in PDF, EPUB and Kindle. Book excerpt: Concrete members with steel fibers generally increase the shear and torsional strength of concrete; however, supplementing or replacing the stirrups with steel fibers is still not an accepted practice. Previous studies documented many tests of steel fiber-reinforced concrete (SFRC) beams with and without stirrups that failed in shear. The results indicated that the shear span-depth ratio adversely affects the shear capacity. As part of this experimental study, the picture frame fixture was used to test 20 SFRC samples under in-plane pure shear loading. Samples included hooked, crimped and arched-crimped steel fibers with varying volume fractions. Models for SFRC beam shear strength were reexamined using the current test data. The evaluation indicated that the model developed by Ashour provided the most accurate estimates to account for fibers efficiency in contribution to shear strength. Furthermore, the hooked steel fibers were shown to be more efficient than crimped fibers, and further increase of fiber volume fraction beyond 1 percent of crimped fibers did not result in significant improvements in the shear strength.

This book was released on 2018 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study reports on the shear behavior of fiber-reinforced lightweight concrete (FRLWC) beams reinforced with basalt fiber-reinforced polymer (BFRP) bars. Ten beams (150x250x2400 mm) cast with concrete with and without fibers were tested under fourpoint loading configuration until failure occurred. Two beams were cast without fibers and acted as control while the other eight beams were cast with different types and percentages of fiber. The investigated parameters included the fiber type (basalt, polypropylene, and steel fibers), the fibers volume fraction (0, 0.5, and 1.0%), and the beams' reinforcement ratios (0.95 and 1.37%). Comparison between the experimental results and the analytical models currently available in the literature was performed to assess the applicability of such models for LWC reinforced with BFRP bars. Based on the outcome of the current study, the geometry of fibers played an important role in increasing the number of cracks than those observed in the control beams. The addition of fibers led to a more ductile failure and the rate of crack opening was delayed. Crack width decreased with the increase of the longitudinal reinforcement ratios and the fibers' volume fractions. Increasing the reinforcement ratio resulted in higher stiffness and decreased its deflection at all stages of loading. Beams cast with 1% of basalt, polypropylene, and steel fibers showed an increase in their shear capacities in compared to control beams about 11, 16, and 63%, respectively. The type of fibers significantly affected the gain in the shear capacities of the beams, which can be attributed to the different physical and mechanical properties of the fibers used such as aspect ratios, lengths, geometries, densities, and their bonding mechanisms. Beams cast with 0.5% steel fibers exhibited higher shear capacities than those cast with basalt and polypropylene fibers by 23 and 16%, respectively, whereas the beams cast with 1% steel fibers showed a gain by 47 and 41%, respectively. The predicted shear capacities according to CSA-S806-12 code provisions were conservative with an average ratio Vpred /Vexp of 0.80 (standard deviation, SD = 0.12) for beams without fibers. Good predictions for the shear capacities of the basalt-fiber reinforced concrete beams (BLWC) were provided by the models derived by Shin (1994) and Gopinath (2016) in which the ratios Vpred /Vexp were 1.34 (SD = 0.09) and 1.35 (SD = 0.07), respectively. Also, the model of Shin (1994) predicted well the shear capacities of the polypropylene-fiber reinforced concrete beams (PLWC) with a Vpred /Vexp ratio of 1.34 and SD of 0.18. The models of Gopinath (2016), Ashour A (1992), and Shin (1994) predicted the shear capacities of steel-fiber reinforced concrete beams (SLWC) fairly reasonable with a Vpred /Vexp ratio of 1.01 (SD = 0.06), 1.07 (SD = 0.01) and 1.20 (SD = 0.08), respectively. A new model was proposed to predict the shear capacities of FRWLC beams reinforced with BFRP longitudinal bars. The proposed model predicted well the shear capacities of BLWC beams with a Vpred /Vexp ratio of 1.01 (SD = 0.05) and those of PLWC beams with a Vpred /Vexp ratio of 0.99 (SD = 0.06). The bond factor and the interface bond matrix used were 0.75 and 4.18 MPa, respectively. The proposed model also predicted well the shear capacities of beams cast with SLWC with a Vpred /Vexp ratio of 0.9 when the bond factor and the interface bond matrix were taken equal to 1.00 and 6.8 MPa, respectively.
