Book excerpt: Bridge railings are a safety feature to protect the traveling public by containing and redirecting errant vehicles during run-off-road (ROR) events. Most bridge railing design and evaluation efforts have focused on ROR crashes on high-volume roads. Bridge railings for low-volume roads can be designed for lower impact speeds, so railings designed for high-volume roads are unnecessarily robust for low-volume applications and can be optimized to reduce costs for bridge owners while still providing adequate safety. The aim of this research has been focused on improving the design of two low-volume bridge railing systems for use by the United States Department of Agriculture, Forest Service, Missoula Technology and Development (USDA-FS-MTDD) The first modified barrier system was originally a low-height reinforced concrete barrier designed for National Cooperative Highway Research Program Report No. 350, Test Level 2 standards (NCHRP 350 TL-2). In this research, the barrier was redesigned and optimized to meet Manual for Assessing Safety Hardware (MASH) TL-1 requirements by reducing railing dimensions and reinforcement. Additionally, construction guidance was developed for installation on concrete bridge decks of various thicknesses and overhang widths. AASHTO LRFD Bridge Design Specifications were utilized to evaluate crashworthiness and structural adequacy of the modified barrier design and the deck’s structural adequacy for lateral impact loads, vertical loads of vehicles leaning on the top of the barrier during impact events, and design traffic loads traveling adjacent to the barrier in routine service. The second bridge deck and rail system featured a transverse nail-laminated deck with a low-height timber bridge rail mounted at the edge of the deck. The original deck with railing was crashworthy, but the deck was associated with higher labor costs and more susceptible to deterioration. Further, the agency desired it be used on transverse glulam timber decks. Thus, a study was begun to adapt the railing system for use on transverse glulam decks, which would also increase the durability and likely lower the onsite construction time and labor cost of the deck system. Component tests were performed on the original and modified deck systems to confirm the acceptable performance of the modified system. From the component testing results, the glulam rail and scupper blocks installed on a transverse glulam deck resisted more lateral force, absorbed more energy, and had higher initial linear stiffness as compared to the same rail and scupper blocks installed on a transverse nail-laminated deck. Thus, the low-height, glulam timber bridge railing installed on a transverse, glulam deck will provide equal or greater safety performance as compared to the same bridge rail installed on a transverse, nail-laminated deck. As a result, the low-height, glulam timber bridge rail installed on a transverse glulam deck has also been deemed adequate for use in MASH TL-1 applications.

Available in PDF, EPUB and Kindle. Book excerpt: Several crashworthy wood bridge railings and approach railing transitions have been adapted for use on concrete bridge decks. Included are a glued-laminated timber (glulam) rail, with and without a curb, at Test Level 2 (TL-2), a glulam rail with curb at TL-4, and a glulam curb rail for low-volume roads at TL-1. In adapting the railings from a wood deck to a concrete deck, the critical consideration was railing attachment to the deck.

Book Synopsis Performance of a Thrie-beam Steel-post Bridge-rail System by : James E. Bryden
Download or read book Performance of a Thrie-beam Steel-post Bridge-rail System written by James E. Bryden and published by . This book was released on 1985 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twelve full-scale crash tests were performed to evaluate the performance of a thrie-beam bridge-rail system. The system was tested both with and without a 6-in. curb, with rail height of 33 in.--measured from the deck--for both designs. Also tested were transitions from W-beam guiderail on S3x5.7 posts to thrie-beam guiderail on W6x9 posts, and from the thrie-beam guiderail to the bridge rail. This railing can be used on either new or existing structures, with or without curbs, and requires no attachment to existing railing or structural members. It offers a relatively low-cost railing and because it relies primarily on components common to other barriers, it minimizes maintenance inventory requirements.

This book was released on 2021 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, many timber bridge railings, bridge railings for use on timber deck bridges, and approach guardrail transition systems to accompany these railings, have been developed to meet different impact safety criteria. Through an extensive literature review, the design details of these systems were identified and organized. A survey was then developed and distributed to multiple government agencies and timber industry members to identify their desire for these bridge railing and approach guardrail transition systems to be developed to meet current American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) impact safety criteria. The data provided from the survey was analyzed, and a list of 15 bridge railing systems was created, which included accompanying approach guardrail transitions. This list prioritized the bridge railing systems based upon the number of survey respondents requesting such a bridge railing system. Cost estimates for the research and development of each bridge railing system were also provided in order to proceed into subsequent phases of this research project. The development of a MASH TL-4 glued-laminated (glulam) timber rail with curb bridge railing system was initiated in Phase II. Many similar systems have been developed in the past to meet previous impact safety criteria, but an updated design was necessary to meet current MASH impact safety criteria. Through impact simulations with the computer software program BARRIER VII, a model was created and calibrated to previous crash testing results. After a series of modifications to the bridge railing system represented in the model, including increasing the size and height of multiple components, the simulation effort demonstrated that the modified TL-4 bridge railing was acceptable under the MASH criteria. Additional research on connection details and timber deck strengths, the development of an approach guardrail transition system, and component and full-scale testing programs are yet to be performed in the completion of the Phase II project. An additional project was advanced and involved the adaptation of a previouslydeveloped, MASH TL-1 crashworthy, low-height, curb-type, glulam bridge railing system for transverse, nail-laminated decks to be capable of use on transverse, glulam timber decks, which is part of a Phase III effort. Analysis of the system components and timber deck types led to the creation of a static and dynamic component testing program utilizing two surrogate bridge decks. To date, the test plans and details have been developed, with the construction and testing programs yet to be performed. In the future, results from the component testing program will be utilized to demonstrate that the bridge railing system contains adequate height and strength when used on transverse, glulam timber decks.
