Book excerpt: Post-tensioning and grouting operations can be dangerous if the required care is not taken in planning, in site preparations and in execution. For prestressed concrete a good working environment is also a prerequisite for high quality. Many accidents in this type of work may be attributed to a lack of training, poor supervision, poor planning or over-familiarity with the process. This guide to good practice highlights important safety measures which are particularly applicable to prestressed concrete, dealing with precautions necessary for post-tensioning and grouting operations on site.

Download or read book Post Tensioned Concrete Floors written by Martin Williams and published by CRC Press. This book was released on 2019-08-30 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Post-tensioning is the most versatile form of pre-stressing, a technique which enables engineers to make the most effective use of the material properties of concrete, and so to design structural elements which are strong, slender and efficient. Design in post-tensioned concrete is not difficult and, if done properly, can contribute significantly to the economy and the aesthetic qualities of a building. Post-tensioned floors have found widespread use in office buildings and car park structures, and are also frequently employed in warehouses and public buildings. However, in spite of this, most prestressed concrete texts devote comparatively little attention to floors, concentrating instead on beam elements. This book answers the need for a comprehensive treatment of post-tensioned floor design.

Download or read book Finite Element Analysis of Prestressed Concrete Structures Using Post Tensioning Steel written by Yu Huang and published by Cambridge Scholars Publishing. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book deals fundamentally with the basic philosophy, principles and the application of prestressing in structural elements. It also covers the detailed engineering of the structural elements with prestressing forces in terms of analysis and design. Different systems of prestressing, losses in prestressing and evaluation of capacity of prestressed concrete sections in flexure, shear and torsion, the force flow due to prestressing at anchorage zones, the time dependent effects due to creep and shrinkage of materials are explained. The design of prestressed concrete elements is covered with a holistic concept. In case of indeterminate structures, the effect of prestressing while satisfying the compatibility conditions has been clearly explained. The necessary philosophy and the design procedures of partially prestressed elements have been specifically dealt with. Accepted National and International Code provisions for design of prestressed concrete elements under the effect of the various loads have been elaborately discussed with worked out examples.

Download or read book Grouting of Tendons in Prestressed Concrete written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2002-01-01 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prestressed Concrete is a very efficient form of construction; it takes advantage of the strength of concrete in compression. Developed mainly over the second part of the 20th century, it has proven to be reliable and durable. However, in the 1990's some cause for concern was discovered, first in the UK and followed by many other countries of the world. It appeared that the grout, an important means of protection of the steel against corrosion for internally ducted tendons, was in some cases inadequate. Major investigations followed including physical intrusive examination of ducts, mainly in bridges, and re-writing of procedures, processes and specifications, and in 1998 FIP launched a Task Group to review their advice note "Guidelines for Grouting" which had first been published in 1990. The merger of FIP and CEB in 1998 brought this under the auspices of fib. Structural deficiencies have only been found in a small number of bridges and in most of these cases the cause is clearly identifiable as either design detailing, workmanship or materials. In the UK, the Concrete Society report TR47 "Durable Post-tensioned Concrete Bridges" had been published in 1996, which was the culmination of four years of investigative research, and contained major new specifications and procedures aimed at improving the quality of grouting. In the USA, the Post Tensioning Institute published in 2001 their guide "Specification for Grouting of Post-Tensioned Structures", which also represented major steps forward in materials and testing requirements. The American Segmental Bridge Institute has set up a Committee to re-examine their guidelines, as have many other National Bodies worldwide. In Europe, France has issued a "Fascicule No. 65A" covering requirements for grouting and there are many developments in hand in other countries. Also in Europe, a European Technical Approval Guideline (ETAG) has been published for approval of post-tensioning systems which covers several aspects of grout and grouting. In November 2001 an international workshop was held in Ghent, Belgium on "Durability of Post-Tensioning Tendons" [see fib Bulletin 15] at which international experience was exchanged. The theme was clearly apparent; those bridge owners that have looked, have found some problems with a few of their post-tensioned bridges. In most cases steps are being taken to repair existing bridges, where considered necessary, and to improve future construction by reviewing national specifications. Emphasis is being put on a multi-layer protection strategy whereby protection against corrosion is provided by waterproofing, dense impermeable concrete, sealed ducts and good quality grout. Design detailing and rain water management are seen as important aspects. It was, therefore, timely for fib to publish state-of-the-art guidelines to assist in developing and improving the quality of a major line of defence against corrosion, the cement grout. This document represents a consensus view of current practitioners of what is a rapidly developing awareness of some of the shortcomings of previous practice and suggests improvements. This document is a major update of the previous FIP Guidelines and may be taken as a future basis for updating EN 445-447. New areas include understanding of the deleterious effects of an unstable grout, bleeding and how to avoid it, the importance of training and proper procedures, mix design and testing/trials and some new test procedures. It is now understood and generally accepted that the properties of common grout made from cement and water can be very variable and sometimes unpredictable and such grout is not recommended.
