Download or read book Collapse analysis of externally prestressed structures written by Jens Tandler and published by diplom.de. This book was released on 2014-04-11 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Introduction: This dissertation is an investigation into the behaviour of externally prestressed structures, focusing on bridge box girders, at the ultimate limit state. The main objective is the ductility and the tendon stress increase up to failure of externally prestressed structures. Their behaviour will be compared to internally prestressed structures. The dissertation may have valuable information for the first stages of the design process for medium span bridges as the study is concerned about the overall safety and efficiency of prestressed concrete bridges by the means of ductility. The aim is also to provide information about the tendon stress at failure, which is required for the detailed design.

Book Synopsis Evaluation of Planless Prestressed Concrete Double T-beam Bridges Without Experimental Load Rating Tests by : Byungkwan Kim

This book was released on 2016 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical load rating methods were conducted to evaluate prestressed concrete double T-beam bridges without design plans. Due to having no design plans, concrete and prestressing properties were assumed to estimate the number and location of the prestressing strands. A range of required prestressing area was estimated based on Magnel Diagram. The location of the strands (i.e., eccentricity) was verified by a Hilti Ferroscan system to reduce the range of required prestressing area. AASHTOWare BrR load rating analysis was generated based on the estimated prestressing area with multiple prestressing diameters. Because the AASHTOWare BrR load rating results were analyzed based on several assumptions, a "confidence level" for the assumptions was computed to reflect the accuracy and reliability of each assumption. The confidence level of the assumptions was considered for the distribution factor, concrete properties, prestress losses, prestessing forces, prestressing diameter, number of prestressing strands, eccentricity, and bridge condition and performance with an overall reduction factor of 80%. The AASHTOWare BrR load rating results were adjusted according to an average of the confidence level of the assumptions as a reduction factor. Six prestressed double T-beam bridges located in Doña Ana County, New Mexico (Bridge 8761, 7705, 7712, 7710, 7723, and 7713) were evaluated using the developed procedures. Bridge 8761 has original design plans and calculations, and proof test results unlike the other bridges. However, Bridge 8761 was treated as a bridge without plans to validate the estimation procedures and results. From the results of Bridge 8761, the adjusted load rating and proof testing results had a lower load rating factor compared to the original design plan results, indicating the procedure provides conservative ratings. Furthermore, the lowest adjusted load rating results had 6% lower rating factors than the proof test results, which was more conservative. From the adjusted load rating results, Bridge 7705, 7712, 7723, and 7713 do not need to have experimental load rating test performed. However, it is recommended that experimental load rating tests be conducted for Bridge 7710 to assure proper safety. This analytical load rating procedure provided an initial load rating estimation to avoid performing experimental load rating tests for saving cost and time.
