Available in PDF, EPUB and Kindle. Book excerpt: The loading configurations included using one, two or four symmetrically placed concentrated loads on simply supported spans. The theory predicted the shear strength of the beams in the present study well. When beams from previous investigations were included, the theory also gave good prediction of the shear strength. Apart from this, comparisons of shear strength were also made with the predictions by the shear design provisions contained in the Australian Standard AS 3600 (1994), American Concrete Institute Building Code ACI 318-95, Eurocode EC2 Part 1 and Canadian Standard CSA A23.3-94. The AS 3600 method was found to give the best correlation with the test results among all the code methods.

Download or read book Ultra High Performance Concrete UHPC written by Ekkehard Fehling and published by John Wiley & Sons. This book was released on 2015-04-20 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since. Ultra high performance concrete (UHPC) is a milestone in concrete technology and application. It permits the construction of both more slender and more durable concrete structures with a prolonged service life and thus improved sustainability. This book is a comprehensive overview of UHPC - from the principles behind its production and its mechanical properties to design and detailing aspects. The focus is on the material behaviour of steel fibre-reinforced UHPC. Numerical modelling and detailing of the connections with reinforced concrete elements are featured as well. Numerous examples worldwide - bridges, columns, facades and roofs - are the basis for additional explanations about the benefits of UHPC and how it helps to realise several architectural requirements. The authors are extensively involved in the testing, design, construction and monitoring of UHPC structures. What they provide here is therefore a unique synopsis of the state of the art with a view to practical applications.

This book was released on 2013-12-04 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research is to test a series of UHPC specimens to investigate the shear failure responses in beams. Additionally, this research will also investigate the tensile properties of UHPC to assist in determining the relevant shear properties. Two series of specimens were created for testing: small-scale beam specimens for load-displacement behavior analysis under four-point bending and UHPC prisms for determining the effects of tension stiffening. Both sets of specimens were created using ASTM Grade 60 steel and high strength steel for the primary reinforcement. Finally, numerical analyses using finite element analysis software, based on both continuum and macroelement models, of the UHPC specimens were carried out based on the modified compression field theory (MCFT) to verify and expand upon the experimental results.

Download or read book Behavior of High Performance Steel as Shear Reinforcement for Concrete Beams written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to study the feasibility of using high performance steel as shear reinforcement for concrete beams. High performance steel is characterized by enhanced corrosion resistance and higher strength in comparison to conventional Grade 60 steel reinforcement. Advantages of using higher strength steel include the ability to design for longer span lengths and/or reducing the amount of material needed for design. This could greatly reduce the overall costs of construction for future structures. Nine reinforced concrete beams were constructed using No. 9 longitudinal bars and No. 3 bars for the stirrups. The main variables considered in the study are the stirrup spacing and the type of reinforcing steel material. Testing was performed using a single concentrated load positioned closer to one end of the beam, which allowed for two tests per beam. Research findings indicate that using MMFX stirrups increases the overall shear strength and enhances serviceability by distributing cracks and reducing crack width. Pairing high performance longitudinal and transverse reinforcement shows an optimum design in terms of strength gain and reduction in crack width. Enhanced serviceability behavior can be attributed to the better bond characteristics of MMFX steel in comparison to conventional Grade 60 steel. Test results suggest that combining high performance steel with high strength concrete could lead to a better utilization of the materials. Analysis shows that the ACI 318-05, CSA, and AASHTO LRFD design codes can conservatively be used for the design of high performance steel up to a yield strength of 80 ksi. Detailed analysis using the Modified Compression Field Theory can be used to accurately predict the behavior of the beams.

Download or read book Evaluation of the Shear Strength of Ultra high Performance Concrete written by Danielle M. Voytko and published by . This book was released on 2021 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
