Book Description
The book is recommended for the research graduate students perusing their research in the fields of high performance and high strength concrete with special reference to shear properties. The findings of the research can also be used by the graduate students interested in the in-depth analysis of Building Codes provisions of High Strength and High Performance Concrete. The book is recommended for use of the students interested to study the behavior of High Strength Concrete beams as well. The book involves analytical study of the high strength concrete beams on the basis of various parameters such as longitudinal steel ratio, shear span to depth ratio, web reinforcement etc. The contribution of web steel to the shear capacity of the beams has also been analyzed. 70 beams have been tested to verify these parameters. The results of the shear capacity of the high strength concrete beams have been compared with the provisions of the various building and bridges codes, most commonly practiced by the designers and engineers of concrete structures. The study of disturbed region in concrete structures provides the basic knowledge for the detailed research by the interested students....

Evaluation of the Shear Strength of Ultra-high Performance Concrete

Languages : en
Pages : 160
Book Description
Ultra-High Performance Concrete (UHPC) is a cementitious concrete with reinforcing fibers that has exceptionally high compressive, tensile, flexural, and bond strengths, but not much is known about its shear strength. It is typically composed of cementitious material, fine sand, steel fiber reinforcement, admixtures, and water. The inclusion of steel fiber reinforcement and admixtures lead to higher costs than conventional concrete. Due to its high cost, UHPC applications in the United States have been associated with connections, in which its high strength is advantageous and the quantities are small enough to make it cost-effective. Proprietary UHPC mixes have been developed by private companies for use on large-scale projects, but these mixes are not always an option due to high cost. In an effort to make UHPC more accessible, proprietary mixes using local materials and varying percentages of fiber content have been developed. An experimental program was undertaken by the University of Washington, in collaboration with the University of Oklahoma (OU) and Florida International University (FIU), to study one such mix. Seven batches of UHPC were mixed and cast at UW, altering the material sourcing and fiber content. In total, five batches used UW materials and 2% fiber content, 1 batch used UW materials and 1% fiber content, and one batch used OU materials and 2% fiber content. Each batch of UHPC was subject to compression, modulus of elasticity, direct tension, and flexural beam tests. Additionally, they were tested in pure shear using the UW Panel Element Tester. After testing, the experimental data was analyzed to determine the effect of material sourcing and fiber content on UHPC behavior. It was concluded that the effect from material sourcing was negligible, at least partly because critical materials such as fibers and admixtures were obtained nationally and so were unchanged, and the effect from fiber content was little on compression and modulus of elasticity, but large on tension, flexural, and shear. The results were then compared to compression, modulus of elasticity, direct tension, and flexural beam test results from OU that used the same mix design but sourced materials locally and used different mixing equipment and mixing procedures. The conclusions from this comparison were consistent with the initial analysis. Finally, the UW test results were compared with strengths predicted by available equations. However, no such equations exist for UHPC panels tested in pure shear. Therefore, the shear test results were compared with mix parameters such as fiber content, compressive strength, and tensile strength. It was found that the results were best correlated with fiber content and tensile strength. Equations based on these correlations were proposed to estimate shear strength of UHPC.

Reactive Powder Concrete
Author: Yen Lei Voo
Publisher:
ISBN: 9783838324067
Category : Cement composites
Languages : en
Pages : 354
Book Description
Since the beginning of the 20th century, concrete has become the most used construction material. The world production of cement in 2007 was about 2.6 billion tons, compared to just 10 million tons in 1990. Traditionally, concrete was understood as a mixture of cement, water and aggregate but in modern concrete other constituents may also be present such as mineral components, chemical admixtures and fibres. Normal and high strength concretes were developed in the early 1900s and 1950s, respectively, whereas the development of ultra-high- performance concrete known as reactive powder concrete (RPC) was originated in the mid 1990s. RPC is an ultra-high strength cementitious material that contains a high quantity of cement and silica fume, low quantity of water, incorporates large amounts of fibres and exhibits remarkable ductility, durability and strength properties. In this book, the mechanical behaviour of steel fibre reinforced RPC girders is detailed and design models presented. Particular emphasis is placed on non-flexural actions such as shear and bursting where steel fibres are used to replace conventional steel reinforcing bars.

fib Model Code for Concrete Structures 2010
Author: fib - federation internationale du beton
Publisher: John Wiley & Sons
ISBN: 3433030618
Category : Technology & Engineering
Languages : de
Pages : 434
Book Description
The International Federation for Structural Concrete (fib) is a pre-normative organization. 'Pre-normative' implies pioneering work in codification. This work has now been realized with the fib Model Code 2010. The objectives of the fib Model Code 2010 are to serve as a basis for future codes for concrete structures, and present new developments with regard to concrete structures, structural materials and new ideas in order to achieve optimum behaviour. The fib Model Code 2010 is now the most comprehensive code on concrete structures, including their complete life cycle: conceptual design, dimensioning, construction, conservation and dismantlement. It is expected to become an important document for both national and international code committees, practitioners and researchers. The fib Model Code 2010 was produced during the last ten years through an exceptional effort by Joost Walraven (Convener; Delft University of Technology, The Netherlands), Agnieszka Bigaj-van Vliet (Technical Secretary; TNO Built Environment and Geosciences, The Netherlands) as well as experts out of 44 countries from five continents.
