Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Reinforced Concrete Research Council of ASCE. This report reprints a collection of studies advancing the knowledge of the effects of fatigue loading on the structural behavior of prestressed concrete flexural members. Each study represents one phase of an extensive research program conducted at Lehigh University and sponsored by the Pennsylvania Department of Transportation, the Federal Highway Administration, and the Reinforced Concrete Research Council. The four areas of study are: the effect of stress gradient on the probable fatigue life of plain concrete, as related to the compression block of prestressed concrete flexural members; the probable fatigue life of seven-wire prestressing strand under repeated loading of either constant or varied magnitude; the probable fatigue life of prestressed concrete flexural members, as limited by the fatigue failure of the prestressing strand; and the susceptibility of prestressed concrete flexural members to fatigue failure in shear. This report provides guidance to structural engineers faced with the design or analysis of prestressed concrete flexural members and to research engineers who are seeking to extend the knowledge of structural behavior as affected by repeated loading.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past 20 years, the Transport and Road Research Laboratory has carried out a co-ordinated programme of fatigue testing, including work on the fatigue performance of reinforced and pre-stressed concrete beams. The research has led to a better understanding of the fatigue behaviour of plain concrete, the various types of reinforcing bars in air and concrete, continuous welded, lapped and coupled bars, and the effects of corrosion. The work of TRRL and many other organizations is reviewed and a summary of current design rules with recommendations for assessing the fatigue life of new structures in service is given.

This book was released on 2010-08 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improvement in the short-term behavior of deficient reinforced concrete (RC) beams is very well known through extensive testing of reinforced concrete beams strengthened by externally bonded carbon fiber reinforced polymer (CFRP) strips. However, long-term performance of such beams needs to be assessed before the method can gain full acceptance. Modeling of the overall system of CFRP strengthened RC beams requires modeling of the individual components that ultimately leads to failure i.e., concrete, CFRP and concrete-CFRP interface. Component elasto-damage constitutive models are developed for concrete crushing, CFRP plate rupture and concrete-CFRP interface failure, calibrated by data from both suitably designed experiments and from experiments reported in literature, and are utilized to investigate the low cycle fatigue behavior of reinforced concrete beams strengthened by CFRP strips. The predictive ability of the models is tested by comparison to data from two different beam strengthening schemes i.e., with end anchorage and without end anchorage.

This book was released on 2012-02 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Typical strengthening systems for reinforced concrete structures are based on the use of organic matrices and carbon or glass fibers. In this book a new type of strengthening system is investigated and proposed. The system consists of high strength steel fiber tapes impregnated by a fireproof inorganic matrix. This retrofit system was used successfully to strengthen reinforced concrete beams.The results indicate that the failure of the strengthened beams was driven by yielding of the steel reinforcement in the tension face of the beams, followed by a local slippage of the steel cords from the inorganic matrix. In conclusion, the strengthening system can provide a great alternative to commercially available systems. The developed system was also investigated for the evaluation of its durability by testing R/C beams under high cycle fatigue loading bending conditions. The results show that the fatigue life of reinforced concrete beams can be significantly extended through the use of the externally bonded system. Although the fiber strengthening system increases the fatigue life of beams, the failure mechanism remains the same in both strengthened and non-strengthened beams.

Available in PDF, EPUB and Kindle. Book excerpt: The in situ rehabilitation or upgrading of reinforced concrete members using bonded steel plates is an effective, convenient and economic method of improving structural performance. However, disadvantages inherent in the use of steel have stimulated research into the possibility of using fibre reinforced polymer (FRP) materials in its place, providing a non-corrosive, more versatile strengthening system. This book presents a detailed study of the flexural strengthening of reinforced and prestressed concrete members using fibre reinforces polymer composite plates. It is based to a large extent on material developed or provided by the consortium which studied the technology of plate bonding to upgrade structural units using carbon fibre / polymer composite materials. The research and trial tests were undertaken as part of the ROBUST project, one of several ventures in the UK Government's DTI-LINK Structural Composites Programme. The book has been designed for practising structural and civil engineers seeking to understand the principles and design technology of plate bonding, and for final year undergraduate and postgraduate engineers studying the principles of highway and bridge engineering and structural engineering.

Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Report 678: Design of FRP Systems for Strengthening Concrete Girders in Shear offers suggested design guidelines for concrete girders strengthened in shear using externally bonded Fiber-Reinforced Polymer (FRP) systems. The guidelines address the strengthening schemes and application of the FRP systems and their contribution to shear capacity of reinforced and prestressed concrete girders. The guidelines are supplemented by design examples to illustrate their use for concrete beams strengthened with different FRP systems. Appendix A of NCHRP Report 678, which contains the research agency's final report, provides further elaboration on the work performed in this project. Appendix A: Research Description and Findings, is only available online.

Download or read book The Effect of Fatigue on Understrength Shear-critical Reinforced Concrete Beams Reinforced with External CFRP Stirrups written by Andrew M. Budek and published by . This book was released on 2007 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is a technical report detailing the testing of six understrength reinforced concrete beams subjected to fatigue loading. Three beams were tests as-built, and three were reinforced with external carbon fiber stirrups. Tests to failure of as-built/retrofitted beam pairs were conducted statically, and after 100,000 and 1,000,000 cycles respectively. The beams subjected to fatigue loading were first loaded quasi-statically to first cracking. The load amplitude for fatigue was set to give a peak load at 75% of that for first cracking. The as-built beams failed through rupture of the internal steel shear reinforcement. The CFRP beams failed through rupture of the concrete under the CFRP-concrete interface. The load distribution mechanism in the fatigue loaded CFRP-reinfored beams was different from the statically loaded example in that the strains in the CFRP were substantially higher through the post-fatigue loading regime. This suggests that the crack surfaces were 'worked', or polished by fatigue loading, degrading the concrete shear-resisting mechanism. The CFRP-reinforced beams also displayed different crack patterns from the unreinforced examples, in that a small number of wide shear cracks formed, inclined at 45 [degrees]. Cracking in the as-built specimens was more widely spread, and the cracks were narrower. The force-displacement response of the CFRP-reinforced beams was found to be bilinear in all cases, as was the response of the as-built beam subjected to 1,000,000 cycles. The as-built beams subjected to no cyclic loading, and 100,000 cycles, had a linear force-displacement response. An equation is presented which predicts ultimate shear strength of the CFRP-reinforced beams within an LRFD framework."--Abstract (p. [1]).
