Download or read book Bond Strength of Grouted Reinforcing Bars written by David Darwin and published by . This book was released on 1993 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of hole preparation method, grout type, hole diameter, bar size, embedment length, cover, reinforcing bar deformation pattern, bar surface condition (epoxy coated or uncoated), orientation of the installed bar, and concrete strength on the bond strength of grouted reinforcing bars are described. Hole preparation methods, using a high-speed vacuum drill or a hand-held pneumatic hammer drill, and cleaning methods, using a fiber bottle brush with water, a fiber bottle brush without water, or compressed air only, are compared. Two capsule systems, two two-component grout systems, and two nonshrink grout systems are evaluated. Hole diameters range from 0.75 to 1.5 in. for No. 5 bars; 1.25 in. diameter holes are used for No. 8 bars. Embedment lengths range from 4 to 12 in. for No. 5 bars and from 6 to 15 in. for No. 8 bars. 1.5 and 3.0 in. covers are used. Two bar deformation patterns are evaluated. Bar installations include vertical, sloped, and horizontal. Concrete strengths range from 2700 to 5900 psi. Test results are used to develop rational design and construction requirements. A standard test to establish the Strength Class of a grout for anchoring reinforcing bars is proposed. In addition, a test method currently in use by one state department of transportation as a technique for proof-testing grouted reinforcement in the field is evaluated.

Download or read book Ground Anchors and Anchored Structures written by Petros P. Xanthakos and published by John Wiley & Sons. This book was released on 1991-09-03 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treating anchorages as a direct application of the laws of statics and the theories governing the transfer of load, this book focuses on designs that are safe and reasonably priced. It is divided into two parts. Following a general introduction in the first chapter, Part One goes on to explore anchor systems, components, installation and construction details. Presents special anchor systems such as extractable, compression-type, multibell, and regroutable anchors. Analyzes the transfer of load and its relation to failure modes and anchor load capacity; deals with design considerations; covers mechanisms and types of corrosion; and details anchor stressing, testing programs, and evaluation standards. Part Two considers uses and applications and design aspects of anchored structures; presents design examples of practical value and reasonable simplicity; and incorporates examples and case histories.

Download or read book Anchorage of Large diameter Reinforcing Bars Grouted Into Ducts written by and published by . This book was released on 2008 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of a few large-diameter reinforcing bars for the construction of precast concrete bridge bents allows simplified construction by reducing the number of alignments to be made in the field. These bars are grouted into ducts in a precast concrete cap beam. In the proposed precast concrete substructure system, the grouted bars carry tensile forces across the joint between the column and cap beam. This joint is the yielding element in the structural system, and it is crucial to the performance of the structure that the bars yield before other failure mechanisms, including bond failure, occur. However, the cap beam is typically insufficient to anchor the bar, as the depth of the beam is substantially less than the American Association of State Highway and Transportation Officials (AASHTO) bridge code allows. For this project, 17 pullout tests were conducted to determine the bond characteristics and development length of large-diameter bars grouted into ducts. The bars tested ranged in size from #8 to #18. Pullout tests conducted with embedment lengths of at least six bar diameters yielded the reinforcing bar, while the test conducted with an embedment length of 14 bar diameters resulted in bar fracture. The tests and subsequent analysis showed that the bond of these grouted connections is significantly better than the bond of bars cast directly into concrete. The development lengths needed to fully anchor the bar are therefore within the depth available in the cap beam.
