Available in PDF, EPUB and Kindle. Book excerpt: Since bridges cross over large spans of space they often cross significant features such as busy transportation corridors. In addition, bridges carry heavy vehicles sometimes with dangerous cargos, such as fuel and hazardous chemicals. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 307: Recommended Guidelines for the Selection of Test Levels 2 Through 5 Bridge Railings proposes selection guidelines to assist bridge engineers and highway designers in selecting an appropriate test level for bridge railings based on specific site and traffic conditions.

Download or read book Roadside Design Guide written by American Association of State Highway and Transportation Officials. Task Force for Roadside Safety and published by AASHTO. This book was released on 2011 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Roadside Design Guide presents a synthesis of current information and operating practices related to roadside safety and is written in dual units-metric and U.S. Customary. This book is a guide. It is not a standard, nor is it a design policy. It is intended to use as a resource document from which individual highway agencies can develop standards and policies. Although much of the material in the guide can be considered universal in its application, several recommendations are subjective in nature and may need modification to fit local conditions. However, it is important that significant deviations from the guide be based on operational experience and objective analysis. The 2011 edition of the AASHTO Roadside Design Guide has been updated to include hardware that has met the evaluation criteria contained in the National Cooperative Highway Research Program (NCHRP) Report 350: Recommended Procedures for the Safety Performance Evaluation of Highway Features and begins to detail the most current evaluation criteria contained under the Manual for Assessing Safety Hardware, 2009 (MASH). For the most part, roadside hardware tested and accepted under older guidelines that are no longer applicable has not been excluded in this edition." -- AASHTO website.
Book Synopsis Bridge Rail Design Procedure by : Emad Badiee
Download or read book Bridge Rail Design Procedure written by Emad Badiee and published by . This book was released on 2014 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The AASHTO Bridge Specifications recommend a yield line theory analysis to determine the structural capacity of concrete bridge railing based on static strength of concrete. However, this analysis technique has been shown to significantly underestimate the capacity of concrete bridge rails to withstand high speed truck impacts. Traditionally this shortcoming has been mitigated by artificial reductions in bridge rail design loads implemented into the design specifications. Fear of litigation associated with failure of a bridge rail to contain and redirect an errant vehicle has made continuing this policy unacceptable for most state highway agencies. On the other hand, existing barrier design guidelines contained in the Bridge Specifications are based upon National Cooperative Highway Research Program (NCHRP) Report 350. This document has been superseded by the Manual for Assessing Safety Hardware (MASH). The updated performance guidelines incorporate heavier vehicles, higher impact angles, and in one case, higher impact speeds. Full-scale crash testing has shown that the new testing criteria will require stronger and taller barriers. One study has attempted to generate new height and design load requirements for inclusion in the updated Bridge Design Specifications. The load recommended for implementation proved to be extremely high and was not well received by AASHTO's T7 committee on Guardrails and Bridge Rails. Thus, there is a national need for a more thorough evaluation of bridge rail design loads and minimum barrier heights required to meet the MASH guidelines. This thesis presents an improved method based on modified Yield Line Theory and dynamic strength of concrete to estimate the design impact loads to realistic levels without adjustment of the underlying analysis technique. The net effect of applying the new method to the design would be large decreases in the size and cost of bridge railing necessary to withstand the elevated loads. The objective of the research proposed herein includes: (1) Developing improved methods for estimating the structural capacity of bridge rails and cantilevered deck systems based on dynamic strength of concrete, and including the contribution of deflection of deck overhang, moment of inertia of the barrier and deck overhang sections, and mass of the vehicle and barrier and (2) Identifying appropriate design loads for use in the new methods that are representative of MASH recommended crash test conditions TL-2 through TL-5.
Book Synopsis Guidelines for Attachments to Bridge Rails and Median Barriers by : Eric A. Keller
Download or read book Guidelines for Attachments to Bridge Rails and Median Barriers written by Eric A. Keller and published by . This book was released on 2003 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research project was to collect crash test data relating to bridge rails and median barriers, to collect information about common attachments to traffic barriers, and to evaluate this information for the purpose of developing guidelines for the design and placement of traffic barrier attachments. A comprehensive review of full-scale crash testing of bridge rails and median barriers was conducted in order to establish Zones of Intrusion (ZOIs) for traffic barriers. The primary goal of this review was to identify the extent that a pickup or single-unit truck intrudes over the top of a traffic barrier during a vehicular impact.

Book Synopsis Retrofit Railings for Truss Bridges by :
Download or read book Retrofit Railings for Truss Bridges written by and published by . This book was released on 2005 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2003, there were 38 metal truss bridges 50 years of age or older remaining on the State of Texas highway system. Of these 38 bridges, 33 are listed in the National Register of Historic Places. Many of these bridges do not meet current design criteria for rehabilitation due to narrow deck widths, low vertical clearance, and substandard load capacity. In addition, the existing bridge railing systems on these bridges have not been shown to meet the current requirements for safety and strength. This project addressed the design and performance of acceptable traffic railings for existing and new truss bridges in Texas. Specific objectives were to: * design/develop a retrofit railing for low-speed application on the Roy B. Inks Bridge in Llano, Texas; * design/develop a retrofit railing for high-speed application on the U.S. 281 Bridge over the Brazos River in Palo Pinto County, Texas; * identify criteria that can serve as a basis for design exceptions; and design/develop a traffic railing for new truss bridges.
