Strength Design Of Anchorage To Concrete

A comprehensive treatment of current fastening technology using inserts (anchor channels, headed stud), anchors (metal expansion anchor, undercut anchor, bonded anchor, concrete screw and plastic anchor) as well as power actuated fasteners in concrete. It describes in detail the fastening elements as well as their effects and load-bearing capacities in cracked and non-cracked concrete. It further focuses on corrosion behaviour, fire resistance and characteristics with earthquakes and shocks. It finishes off with the design of fastenings according to the European Technical Approval Guideline (ETAG 001), the Final Draft of the CEN Technical Specification 'Design of fastenings for use in concrete' and the American Standards ACI 318-05, Appendix D and ACI 349-01, Appendix B.

Das Buch stellt den aktuellen Stand der kompletten Befestigungstechnik für Beton und Mauerwerk mit Einlegeteilen (Ankerschienen, Kopfbolzen), Dübeln (Metallspreizdübel, Hinterschnittdübel, Verbunddübel, Betonschrauben, Kunststoffdübel) und Setzbolzen umfassend dar. Die Befestigungselemente und ihre Wirkungsmechanismen werden ausführlich beschrieben und das Tragverhalten im ungerissenen und gerissenen Beton untersucht. Weiterhin werden das Korrosionsverhalten, das Verhalten bei Brandbeanspruchung sowie bei Erdbeben- und Schockbeanspruchung behandelt. Von besonderer internationaler Aktualität ist die Bemessung gemäß der europäischen und amerikanischen Normung. Praxisorientierte Kriterien zur Auswahl von Befestigungsmitteln und Bemessungsbeispiele runden das Werk zu einem einzigartigen Handbuch ab.

Strength Design for Reinforced-Concrete Hydraulic Structures is written in sufficient detail to not only provide the designer with design procedures, but also to present examples of their application. A review of general detailing requirements, as well as strength and serviceability requirements, create a strong understanding of the strength-design method. Latter chapters feature examples that demonstrate load-factor application, the design of members subjected to combined flexural and axial loads, the design of members subjected to biaxial bending, and the design for shear strength, including provisions for both special straight and curved members.

Here is a comprehensive guide and reference to assist civil engineers preparing for the Structural Engineer Examination. It offers 350 pages of text and 70 design problems with complete step-by-step solutions. Topics covered: Materials for Reinforced Concrete; Limit State Principles; Flexure of Reinforced Concrete Beams; Shear and Torsion of Concrete Beams; Bond and Anchorage; Design of Reinforced Concrete Columns; Design of Reinforced Concrete Slabs and Footings; Retaining Walls; and Piled Foundations. An index is provided.

As part of the preparation for the fib Model Code for Concrete Structures 2010, task group 4.5 Bond Models undertook a major review of rules for bond and anchorage of reinforcement in the CEB-FIP Model Code 1990. This bulletin presents the outcome of that review, describes the rationale for the revisions and presents the evidence on which the revisions are based. The principle changes in MC2010 include raising the limit on concrete strength that may be used when determining bond resistance to 110MPa, introduction of a coefficient η4 to cater for different reinforcement Classes, and coverage of new construction materials including epoxy coated and headed bars. The format of design rules has been changed to permit more rational treatment of confinement from concrete cover and transverse reinforcement, the contribution of end hooks and bends for tension bars, and end bearing to compression laps. New guidance is provided covering a range of construction techniques and service environments and the influence of long term degradation. Analyses of various aspects of detailing on performance of laps and anchorages have resulted in discontinuation of the ‘proportion lapped’ factor α6, alterations to requirements of transverse reinforcement at laps, and have resolved inconsistencies in provisions for bundled bars between major national codes. Apparent inconsistencies in existing rules for lapped joints and anchorages and between the local bond/slip model and design rules are also resolved, thus allowing integration of application rules and modelling. Finally, the basis for an attempt to introduce simple detailing rules for laps and anchorages is described.
