Available in PDF, EPUB and Kindle. Book excerpt: "This project evaluated bridge railings. State bridge rail designs submitted to the Federal Highway Administration (FHWA) were rated and the best of each type were selected for crash test evaluation. When necessary, the designs were improved and retested. Most of the crash tests were conducted with 4500-lb (2025-kg) cars at 60 mph (95 km/h) and a 25-degree angle and 1800-lb (800-kg) cars at 60 mph (95 km/h) and a 20-degree angle. Performance standards are proposed in 1986 are presented, along with bridge railing geometric design considerations to minimize vehicle snagging. Design drawings of the successfully tested bridge rails are included"--Technical report documentation page

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to develop safer bridge rail and transition designs and to improve design guidelines. Ten bridge railings and two transitions were designed, tested, and evaluated in accordance with American Association of State Highway and Transportation Officials (AASHTO) requirements. The railings were designed using ultimate strength procedures and collision forces from earlier research. Design procedures, railing designs, and test results are presented. All designs demonstrated acceptable collision performance.
Book Synopsis Evaluation of Bridge Approach Rails by : Roger P. Bligh
Download or read book Evaluation of Bridge Approach Rails written by Roger P. Bligh and published by . This book was released on 1992 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recent study on the performance of guardrail-to-bridge rail transitions revealed that many widely used designs do not meet current safety standards. As a result, the Federal Highway Administration (FHWA) requested that the Arizona Department of Transportation verify the safety performance of its standard transition designs. Three transition designs currently being used by ADOT were evaluated through a combined program of computer simulation and full-scale crash testing. The standard ADOT wood post transition, incorporating a channel rubrail and two different sizes of timber posts at a reduced post spacing near the bridge rail end, was found to be in compliance with National Cooperative Highway Research Program (NCHRP) Report 230 performance criteria. The standard ADOT steel post transition with channel rubrail was also found to be in compliance with NCHRP Report 230 requirements when impacted near the end of the bridge rail. However, the upstream end of the steel post transition required modification to eliminate deficiencies identified during testing. The modified design, which terminated the channel rubrail behind a W6x9 guardrail post, was successfully crash tested.

Book Synopsis Design and Evaluation of the TL-4 Minnesota Combination Traffic/bicycle Bridge Rail by : Karla A. Polivka
Download or read book Design and Evaluation of the TL-4 Minnesota Combination Traffic/bicycle Bridge Rail written by Karla A. Polivka and published by . This book was released on 1998 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: A combination traffic and bicycle bridge rail was developed and crash tested. The combination bridge rail was constructed with a standard New Jersey safety shaped barrier and special steel panels formed from tubular steel posts and rails, and square vertical spindle bars. Two cables were installed inside the tubular rails to prevent detachment of large pieces of debris from causing hazardous conditions for vehicles and pedestrians below. Although the crash tested bridge rail was constructed using the New Jersey safety shape, it is believed that this combination traffic/bicycle bridge rail could be easily adapted to other safety shape barriers or rectangular parapets with no need for further crash testing. Due to the modular nature of the steel panel sections, the combination traffic/bicycle bridge rail can be repaired very easily following a vehicular impact. Two full-scale vehicle crash tests were performed on Minnesota's combination traffic/bicycle bridge railing. The tests were conducted and reported in accordance with the requirements specified in NCHRP Report No. 350, "Recommended Procedures for the Safety Performance Evaluation of Highway Features" (1993). The safety performance of the combination traffic/bicycle bridge rail was determined to be acceptable according to Test Level 4 of the NCHRP Report No. 350 criteria

Book excerpt: This study consisted of strength analyses of five in-service bridge railing systems, thirty full-scale vehicle crash tests on those railing systems and on a load measuring wall, the development of recommended design guidelines and development of recommended performance standards. The spectrum of vehicles addressed ranged from an 1,800 lb Honda sedan to a 32,000 lb intercity bus. Some of the in-service railings were found to have poor performance in full-scale crash tests.
