Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Post-tensioning concrete technology increases the resistance of flexural concrete members. This technology allows for the production of slenderer sections, and sequentially less usage of material preserving the sustainability concept in construction engineering. Post-tensioning process can be done using bonded or unbonded steel tendons. The unbonded tendons are thought to have better resistance to corrosion for structures exposed to severe environmental conditions. The unbonded tendon's steel strands are painted with grease and covered with plastic sheathing to prevent the moisture from reaching the steel strands thus they can provide high corrosion resistance. According to the ACI 318-19 and other codes of practice, the stress in the unbonded tendon at the ultimate limit state is limited to less than or equal to the tendon's yield stress. On the other hand, the bonded tendon's stress at this state is determined to be more than or equal to the tendon's yield stress. This limitation for the unbonded tendons restrained the widespread usage of the unbonded system. Through this research, six-simply supported one-way slabs; two with bonded tendons, two with unbonded tendons and two with unbonded tendons and non-prestressing steel reinforcement are tested in flexure to failure. The post-tension slabs are of 4.0-meters in span and the flexural tests are carried in the AUC structural engineering laboratory in a four-point loading scheme. The ultimate stress of the unbonded tendons are measured at the failure stage. The results of both systems are compared against each other and against the provisions of the ACI 318-19. The unbonded post-tension slabs with non-prestressing steel reinforcement showed higher failure loads than the bonded and unbonded slabs without reinforcement. The ACI 318-19 provisions were critically reviewed versus the results of the experimental investigation. The review reveals that the limitation of the unbonded tendon's ultimate stress is not accurate and can be reviewed.

Download or read book Durability of Post-tensioning Tendons written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2006 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The durability of post-tensioning tendons depends undoubtedly on the durability of the materials used, but there are design concept specifics which are also of major importance: the post-tensioning layout and layers of protection such as concrete cover and selected materials in view of the aggressivity of the environment for instance. It is well known that sustainability principles guide the Engineer from the very beginning, at the project conception, during construction and the service life of a structure. Decisions made during conceptual and design stage have the largest influence on the durability and sustainability of post-tensioning tendons. fibBulletin 33 addresses the specifics for prestressed concrete structures: the durability of post-tensioning tendons. It should be noted that it does not repeat topics that have been addressed in other fib bulletins and which is common for both reinforced concrete and prestressed concrete structures. Pre-tensioning, which is used extensively in the precast industry, is not considered here, although conclusions and recommendations herein may, in many cases, also be applicable. This recommendation was prepared by Working Party 5.4.2, Durability specifics for prestressed concrete structures, in cooperation with fib Commission 9,Reinforcing and prestressing materials and systems. A preliminary version of this recommendation served as the basic document for the second workshop on "Durability of post-tensioning tendons", held on 11-12 October 2004 in Zurich. This workshop was a follow-up to the first workshop held in Ghent in 2001. Bulletin 33 includes revisions corresponding to the agreed results of the Zurich workshop.

Download or read book Durability of Post-tensioning Tendons written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2001-01-01 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: In some countries durability problems with post-tensioning tendons have in the past led to fairly restrictive regulations. Improvements to execution procedures have been developed since, and new or improved prestressing systems have been proposed, too. This development was, of course, subject of discussions in fib Commission 9 Reinforcing and Prestressing Materials and Sytems and in IABSE Working Commission 3 Concrete Structures. It was decided to organise a workshop with the aim to review the different aspects of the problems encountered and to discuss solutions available today. Keynote speakers from various countries were invited to contribute. Their papers are published in this bulletin, grouped together under the following themes: Inventory and condition (6 papers) Investigation and repair (5 papers) Technical progress (4 papers) Strategies for improvement (6 papers) Supported by the international federation for structural concrete fib, and the international association for bridge and structural engineering IABSE, the workshop took place on 15-16 November 2001 at Ghent University, celebrating the 75th anniversary of the Magnel Laboratory for Concrete Research, whose director also chaired the Scientific Committee and edited the bulletin. It needs to be emphasised that in the bulletin invited experts present their individual views. Although not yet discussed in any of the association's working bodies, the highly topical contents of the bulletin is believed to be of general interest to fib's members and to document a starting point for future work in this field. Therefore, the Council of fib agreed to exceptionally publish these papers within fib's series of Bulletins.
