Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 679: Design of Concrete Structures Using High-Strength Steel Reinforcement evaluates the existing American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specifications relevant to the use of high-strength reinforcing steel and other grades of reinforcing steel having no discernible yield plateau. The report also includes recommended language to the AASHTO LRFD Bridge Design Specifications that will permit the use of high-strength reinforcing steel with specified yield strengths not greater than 100 ksi. The Appendixes to NCHRP Report 679 were published online.

Book Description
In this chapter an experimental investigation is carried out on high strength concrete beams without transverse reinforcement and with transverse reinforcement. The beams were tested in bending under two concentrated loads using the technique of digital image correlation. In the test setup, the shear zone which is defined by the area of beam between the support point and the loading point was studied by the camera of high resolution. The Gom-Aramis software was used to record and analyse the numerical images by determination of the deformation of concrete in the compressed zone of the beam, to calculate the opening, the spacing and the length of the diagonal cracks. The experimental shear strength of the beams was compared with the theoretical values predicted by the different design codes, such as the American ACI 318, the British Standard BS 8110, the European Eurocode 2, the New Zealand NZS 3101 and the Indian Standard IS456. The results show that all the design codes underestimate the contribution of high strength concrete to the shear resistance of reinforced concrete beams, and greatly overestimate the contribution of transverse reinforcement. The European Eurocode 2 is the only one among the four code models that gives the best prediction of the ultimate shear strength of high strength concrete.

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....
