Available in PDF, EPUB and Kindle. Book excerpt: Prestressed Tee-beams constructed by the split-beam method were tested to failure in flexure to study the behavior and ultimate strength of these beams and to compare their flexural characteristics with those of prestressed beams of conventional construction. Results showed that composite split-beams behaved similarly to the monolithically constructed beams on the basis of flexural response and ultimate load.

Download or read book Flexural Behavior of Concrete Beams Prestressed with Bonded and Unbonded Tendons written by Adi Abu-Obeidah and published by . This book was released on 2017 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of unbonded tendons in prestressed concrete beams has been widely utilized in bridges, parking structures, and residential buildings for strengthening, rehabilitation or repair of such members. With the growth of live load and the increase of damaged concrete members, there is a need to develop and utilize new techniques for more efficient and improved designs in prestressed concrete members. This research presents an experimental and analytical investigation for the use of combination of bonded and unbonded tendons in the same concrete members. With the availability of high strength concrete, as well as the development of new prestressing technologies, the process can be easily performed at the site for repair or capacity upgrading resulting in longer spans for the same section depth or shallower sections. There is a knowledge gap on the behavior of concrete beams prestressed with hybrid tendons and a need to fully understand their overall behavior under full service loads. The hybrid technique introduces unbonded CFRP tendons, which is resistant to corrosion. In addition, CFRP tendons exhibit linear stress-strain relationship resulting in more accurate predictions for the tendon stress at ultimate. This hybrid system presents a challenge in developing an analytical model that could predict their behavior since the unbonded tendon is not bonded with the concrete. This investigation included the testing of 15 High Strength Concrete (HSC) beams prestressed with hybrid tendons. Results from the experimental study included number of cracks, load-deflection behavior, and strains in prestressing strand, reinforcing steel, and concrete. This study emphasizes the prediction of the ultimate stress of the unbonded tendon (fps) in unbonded or hybrid system for computing the ultimate moment resistance. Finite element modeling and analysis of various beams is performed. Based on a comparison of equations available in the literature as well as code provisions with the experimental results, a simplified prediction equation for predicting the stress in the unbonded tendons at ultimate is recommended.

Download or read book ON THE FLEXURAL BEHAVIOR OF CONCRETE BEAMS PRESTRESSED WITH UNBONDED INTERNAL AND EXTERNAL TENDONS (UNBONDED TENDONS, BEAMS). written by FADI MAAZ ALKHAIRI and published by . This book was released on 1991 with total page 916 pages. Available in PDF, EPUB and Kindle. Book excerpt: from 15 different investigations. Excellent correlation was obtained between predicted vs. experimental results. The present investigation suggests that shear deformations may have some effect on the stress increase in unbonded tendons for beams having low span-to-depth ratios, while eccentricity variations in external tendons significantly affect the overall behavior for beams having high span-to-depth ratios.

This book was released on 2017-08-08 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book combines history with academic notes for use at the university level, presenting design examples from actual jobs with applications and detailing for the practicing engineer. Chapter 1 tells the history of post-tensioned concrete as only Ken Bondy can tell it. Chapters 2-8 are the notes Dirk Bondy uses to teach Design of Prestressed Concrete Structures at UCLA and Cal Poly-San Luis Obispo. Chapters 9-13 are design examples that address many of the decisions faced by practicing engineers on typical projects. Chapters 13-14 cover the art of detailing and observing the construction of post-tensioned concrete. This knowledge was obtained over many years of working on our own projects and listening and learning from the the pioneers of post-tensioned concrete. Chapter 15 covers the slab on grade industry, which represents more sales of post-tensioning tendons than all other post-tensioning applications combined. Chapter 16 discusses the challenging application of post-tensioning-external post-tensioning.

This book was released on 2013-03-14 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 24 (thesis year 1979) a total of 10,033 theses titles from 26 Canadian and 215 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 24 reports these submitted in 1979, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

This book was released on 2020-05-28 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book details the theory and applications of finite element (FE) modeling of post-tensioned (PT) concrete structures, and provides the updated MATLAB code (as of 2019). The challenge of modeling PT prestressed concrete structures lies in the treatment of the interface between the concrete and prestressing tendons. Using MATLAB, this study develops an innovative nonlinear FE formulation which incorporates contact techniques and engineering elements to considerably reduce the need of computational power. This FE formulation has the ability to simulate different PT frame systems with fully bonded, fully unbonded or partially bonded tendons, as well as actual sliding behavior and frictional effects in the tendons. It also allows for the accurate simulation of anchor seating loss.
