This book was released on 2015 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reinforced concrete (RC) pipes are widely used as open channels (non-pressurized pipes) for sewage and storm water conveyance. RC pipes have generally achieved a reliable long-term performance. Depending on multiple parameters (e.g. pipe diameter, pipe wall thickness, required strength, etc.) the pipe may have up to three welded reinforcement cages in order to resist anticipated loads. Each cage is an assembled unit of steel reinforcement consisting of circumferential and longitudinal bars or wires. The fabrication process of a steel cage reinforcement is time and labour consuming. Thus, eliminating the steel cage reinforcement will yield an overall reduction in the production cost of precast concrete pipes. Dispersed steel fibres can be an effective alternative for the reinforcement of concrete pipes. The aim of this study is to explore using steel fibres as reinforcement in dry-cast concrete pipes. Mechanical properties of dry-cast steel-fibre reinforced concrete (DCSFRC) fabricated using multiple steel fibre types at various dosages were characterized. Consequently, precast pipes reinforced with Dramix RC-65/35-CN and Dramix RC-80/60-CN fibres at various dosages were fabricated. An extensive experimental program was carried out in order to evaluate the structural performance of the full-scale steel fibre-reinforced concrete (SFRC) pipes that were produced in comparison to plain concrete (PC) and RC pipes. Precast pipes had internal diameters of 300, 450, and 600 mm as well as a Type C wall thickness. The structural performance of pipes was characterized using both the continuous and cyclic three-edge-bearing tests (TEBT). Furthermore, the soil-pipe interaction of buried full-scale SFRC pipes was investigated. Finally, a three dimensional non-linear finite element model of the TEBT of SFRC pipes was developed. Subsequently, a parametric study covering multiple pipe configuration and reinforcement parameters was conducted. Results showed that hooked-end fibres with the largest fibre aspect ratio (Dramix RC-80/60-CN) induced the best flexural performance of DCSFRC specimens while crimped fibres (Novocon XR) were the least effective in enhancing the flexural strength and post-peak behaviour of DCSFRC. The load carrying capacity of SFRC pipes increased with increased fibre dosage. Results of the TEBT for 300 mm diameter pipes showed that the reinforcement specified for Class V pipes in ASTM C76 Standard Specification For Reinforced Concrete Culvert, Storm Drain, And Sewer Pipe could be achieved using a steel fibre dosage of 20 kg/m3, while a fibre dosage of 30 kg/m3 was sufficient for 450 and 600 mm diameter pipes to satisfy the same strength class (Class V). Furthermore, provided using a sufficient fibre dosage, SFRC pipes exhibited higher residual strengths and less deformations than that of RC pipes when subjected to small to moderate loading levels. In addition, results showed that using a hybrid system of short (Dramix RC-65/35-CN) and long (Dramix RC-80/60-CN) fibres did not result in synergetic effects. Full-scale testing results of buried SFRC pipes indicated that the pipes could sustain live loads consisting of a fully loaded 625CL Standard Ontario Truck without exhibiting any cracks or significant deformations, even when the pipe was installed in the least quality installation type (Type IV). This indicated that the current design recommendations for the pipe wall thickness in ASTM C76 (Type C wall) are overly conservative. Furthermore, it was found that the post-cracking behaviour of buried SFRC pipes was more sensitive to the installation type than to the type of steel fibre reinforcement. Finally, the findings of the parametric study were presented in a tabular form that can be used as a design aid supplementary to the newly released ASTM C1765 Standard Specification for Steel Fiber Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe. The experimental findings of this study should assist the precast concrete industry in producing more economical SFRC pipe without the need for costly and time consuming welded steel cage reinforcement. The numerical and analytical study findings provided a simple and rational tool for the design of such SFRC pipes.

This book was released on 2020-08-01 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first international FRC workshop supported by RILEM and ACI was held in Bergamo (Italy) in 2004. At that time, a lack of specific building codes and standards was identified as the main inhibitor to the application of this technology in engineering practice. The workshop aim was placed on the identification of applications, guidelines, and research needs in order for this advanced technology to be transferred to professional practice. The second international FRC workshop, held in Montreal (Canada) in 2014, was the first ACI-fib joint technical event. Many of the objectives identified in 2004 had been achieved by various groups of researchers who shared a common interest in extending the application of FRC materials into the realm of structural engineering and design. The aim of the workshop was to provide the State-of-the-Art on the recent progress that had been made in term of specifications and actual applications for buildings, underground structures, and bridge projects worldwide. The rapid development of codes, the introduction of new materials and the growing interest of the construction industry suggested presenting this forum at closer intervals. In this context, the third international FRC workshop was held in Desenzano (Italy), four years after Montreal. In this first ACI-fib-RILEM joint technical event, the maturity gained through the recent technological developments and large-scale applications were used to show the acceptability of the concrete design using various fibre compositions. The growing interests of civil infrastructure owners in ultra-high-performance fibre-reinforced concrete (UHPFRC) and synthetic fibres in structural applications bring new challenges in terms of concrete technology and design recommendations. In such a short period of time, we have witnessed the proliferation of the use of fibres as structural reinforcement in various applications such as industrial floors, elevated slabs, precast tunnel lining sections, foundations, as well as bridge decks. We are now moving towards addressing many durability-based design requirements by the use of fibres, as well as the general serviceability-based design. However, the possibility of having a residual tensile strength after cracking of the concrete matrix requires a new conceptual approach for a proper design of FRC structural elements. With such a perspective in mind, the aim of FRC2018 workshop was to provide the State-of-the-Art on the recent progress in terms of specifications development, actual applications, and to expose users and researchers to the challenges in the design and construction of a wide variety of structural applications. Considering that at the time of the first workshop, in 2004, no structural codes were available on FRC, we have to recognize the enormous work done by researchers all over the world, who have presented at many FRC events, and convinced code bodies to include FRC among the reliable alternatives for structural applications. This will allow engineers to increasingly utilize FRC with confidence for designing safe and durable structures. Many presentations also clearly showed that FRC is a promising material for efficient rehabilitation of existing infrastructure in a broad spectrum of repair applications. These cases range from sustained gravity loads to harsh environmental conditions and seismic applications, which are some of the broadest ranges of applications in Civil Engineering. The workshop was attended by researchers, designers, owner and government representatives as well as participants from the construction and fibre industries. The presence of people with different expertise provided a unique opportunity to share knowledge and promote collaborative efforts. These interactions are essential for the common goal of making better and sustainable constructions in the near future. The workshop was attended by about 150 participants coming from 30 countries. Researchers from all the continents participated in the workshop, including 24 Ph.D. students, who brought their enthusiasm in FRC structural applications. For this reason, the workshop Co-chairs sincerely thank all the enterprises that sponsored this event. They also extend their appreciation for the support provided by the industry over the last 30 years which allowed research centers to study FRC materials and their properties, and develop applications to making its use more routine and accepted throughout the world. Their important contribution has been essential for moving the knowledge base forward. Finally, we appreciate the enormous support received from all three sponsoring organizations of ACI, fib and Rilem and look forward to paving the path for future collaborations in various areas of common interest so that the developmental work and implementation of new specifications and design procedures can be expedited internationally.
