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.

Book excerpt: "TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 474: Service Life of Culverts explores the time during which a culvert is expected to provide a desired function with a specified level of maintenance established at the design or retrofit stage. This study is an update of NCHRP Synthesis 254: Service Life of Drainage Pipe (1998), which itself was an update of NCHRP Synthesis 50: Durability of Drainage Pipe (1978). Developments in plastic pipe, fiber-reinforced concrete pipe, polymeric-coated metal pipe, recycled materials, larger and more diverse structures, and sophisticated analytical soil-structure interaction modeling within the past 15 years led to the development of this report." --
Download or read book Recent Advances in Durability Improvement and Low Carbon Strategy of Engineering Materials and Structures written by Zhongya Zhang and published by Frontiers Media SA. This book was released on 2024-08-28 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming, caused by a significant increase in the concentration of greenhouse gases (GHGs) such as CO2, has become a concern all over the world. The whole process carbon emissions of the civil engineering industry account for nearly 40% of global energy and process-related CO2 emissions, more than half of which come from the process of producing, using, constructing and dismantling in civil engineering materials and structures, resulting in the embodied carbon emissions. With the acceleration of global warming, warmer and uncertain climates will make engineering materials and structures subject to more severe environmental conditions. A series of durability issues will occur more frequently, such as the significant variations of humidity in air, the chloride-induced corrosion caused by the severe chloride ingress, concrete cracking caused by the expansion of rusts, and more severe carbonation of concrete structures due to the increase in CO2 concentration. The adoption of positive measures to address climate change has become a global consensus, as global warming has led to serious threats and challenges to the survival and development of humankind.

This book was released on 2015-03-13 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Durability of Culverts and Special Coatings is intended to provide up-to-date storm drain and culvert material selection methods and techniques to assist the highway engineer in designing culverts. While the program was to consider a variety of materials, the predominant focus was on Aluminized Type 2 corrugated steel pipe (CSP) and its performance versus galvanized CSP. This report is divided into two main sections-field investigation and literature review. The field investigation presents the results of a field evaluation of 32 pipes and their performance relative to that reported in FHWA-FLP-91-006, Durability of Special Coatings for Corrugated Steel Pipe. The present report also includes a review of previous research areas to evaluate conclusions and the utility of existing culvert life prediction methods. The literature review presents a discussion of the various factors affecting culvert durability and its prediction.

Download or read book An Asset Management Approach for Drainage Infrastructure and Culverts written by Mohammad Najafi and published by . This book was released on 2008 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drainage infrastructure systems (culvert, storm sewer, outfall and related drainage elements) are mostly buried underground and are in need of special attention in terms of proactive/preventive asset management strategy. Drainage infrastructure systems represent an integral portion of roadway assets that routinely require inspection, maintenance, repair and renewal. Further challenges are the wide geospatial distribution of these infrastructure assets and environmental exposure. There has been considerable research conducted on culverts, but mostly looked at the problem from a traditional structural/geotechnical perspective. Asset management procedures for culverts and drainage infrastructure systems are complex issues, and can benefit a great deal from an optimal asset management program that draws from programs pertaining to buried pipes. The first and most important step in an asset management initiative is the establishment of mechanism for asset inventory and asset conditions in a format compatible with the routine procedures of field operators and inspectors. The first objective of this research project was to develop field protocols and operational business rules for inventory data collection and management and inspection of drainage infrastructures in terms of types of data to be collected, frequency of inspection, and analysis and reporting mechanisms. After review of these protocols by the project oversight committee, a pilot study was conducted to verify efficiency of their implementation. The condition assessment protocol introduced is useful in evaluating the overall condition of culverts and can be used for decision making regarding the repair, renewal or replacement of culverts. For the second objective of this project, investigators examined the inventory and inspection protocols employed by Ohio Department of Transportation (ODOT) and developed a decision support platform, which establishes a link between the inspection results and appropriate repair, renewal and replacement procedures. After applying the recommended procedures, the transportation agencies can better track the conditions of culverts thereby reducing the risks of culvert failures.
