Book Synopsis Evaluation of Post-tension Strengthened Steel Girder Bridge Using FRP Bars by : Terry J. Wipf
Download or read book Evaluation of Post-tension Strengthened Steel Girder Bridge Using FRP Bars written by Terry J. Wipf and published by . This book was released on 2003 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many state, county, and local agencies are faced with deteriorating bridge infrastructure composed of a large percentage of relatively short to medium span bridges. In many cases, these older structures are rolled or welded longitudinal steel stringers acting compositely with a reinforced concrete deck. Most of these bridges, although still in service, need some level of strengthening due to increases in legal live loads or loss of capacity due to deterioration. Although these bridges are overstressed in most instances, they do not warrant replacement; thus, structurally efficient but cost-effective means of strengthening needs to be employed. In the past, the use of bolted steel cover plates or angles was a common retrofit option for strengthening such bridges. However, the time and labor involved to attach such a strengthening system can sometimes be prohibitive. This project was funded through the Federal Highway Administration's Innovative Bridge Research and Construction program. The goal is to retrofit an existing structurally deficient, three-span continuous steel stringer bridge using an innovative technique that involves the application of post-tensioning forces; the post-tensioning forces were applied using fiber reinforced polymer post-tensioning bars. When compared to other strengthening methods, the use of carbon fiber reinforced polymer composite materials is very appealing in that they are highly resistant to corrosion, have a low weight, and have a high tensile strength. Before the post-tensioning system was installed, a diagnostic load test was conducted on the subject bridge to establish a baseline behavior of the unstrengthened bridge. During the process of installing the post-tensioning hardware and stressing the system, both the bridge and the post-tensioning system were monitored. The installation of the hardware was followed by a follow-up diagnostic load test to assess the effectiveness of the post-tensioning strengthening system. Additional load tests were performed over a period of two years to identify any changes in the strengthening system with time. Laboratory testing of several typical carbon fiber reinforced polymer bar specimens was also conducted to more thoroughly understand their behavior. This report documents the design, installation, and field testing of the strengthening system and bridge.

Download or read book Fibre Reinforced Polymer Strengthening of the Sainte-Emelie-de-l'Energie Bridge written by and published by . This book was released on 2000 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental research project was undertaken to evaluate the need to strengthen exsisting concrete bridges belonging to the Ministere des Transports du Quebec. A typical bridge consisting of a single-span bridge with T-shape sections was identified. Evaluation of the bridge showed that an increase in bending strength and shear strength would be necessory to satisfy current loading conditions and code requiremnts. The increae in bending strength was obtained by bonding carbon-reinforced composie materials to the underface of the beams, with fibre in longitudinal direction. External U-shaped stirrups made of glass-reinforced composite materials were installed on the outside faces of the beams in order to increase their shear strength. This paper presents a selection of experimental results intially obtained on T-section beams, scaled 1:3 with respect to the bridge under consideration. The actual reinforcement scheme selected for the bridge is then presented, accompanied by comments on the construction process. Conventional instrumenation and the fibre optic sensors were incorporated to the repair work in order to evaluate the behaviour of the bridge.

Book excerpt: Rising awareness of and increased attention to sexual harassment has resulted in momentum to implement sexual harassment prevention efforts in higher education institutions. Work on preventing sexual harassment is an area that has recently garnered a lot of attention, especially around education and programs that go beyond the standard anti-sexual harassment trainings often used to comply with legal requirements. On April 20-21, 2021, the National Academies of Sciences, Engineering, and Medicine hosted the workshop Developing Evaluation Metrics for Sexual Harassment Prevention Efforts. The workshop explored approaches and strategies for evaluating and measuring the effectiveness of sexual harassment interventions being implemented at higher education institutions and research and training sites, in order to assist institutions in transforming promising ideas into evidence-based best practices. Workshop participants also addressed methods, metrics, and measures that could be used to evaluate sexual harassment prevention efforts that lead to change in the organizational climate and culture and/or a change in behavior among community members. This publication summarizes the presentations and discussion of the workshop.

Download or read book Condition Assessment of (FRP) Fiber Reinforced Polymer Strengthening of Bridge Components written by Hemachand Pallempati and published by . This book was released on 2015 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber Reinforced Polymers (FRP) is a newly developed composite type of material which have many advantages over conventional materials (concrete and steel) like light weight, non-corrosive nature, design flexibility and quick installation. Due to its superior thermo-mechanical properties, it has emerged as one of the best economical method to strengthen and repair reinforced concrete bridges that were damaged each year due to various reasons like structural deterioration over time, fire accidents, corrosion of steel reinforcement and over height vehicle collision. This research aims to evaluate the long term performance of FRP strengthened bridge components with the help of Pull-Off tests. It will also recommend certain guidelines to be followed during the time of repair for the better performance of FRP. In this study a total of eight concrete bridges in the DFW area, that were damaged in the past and strengthened using Carbon Fiber Reinforced Polymer (CFRP) wrap were identified and later Pull-Off tests were performed on selected test locations of the bridge components as per the specifications of ASTM D7522/D7522M (2009) .After evaluation of the Pull-Off test results it was determined that the overall performance of FRP is good.
