Development Of A Mash Test Level 4 Open Concrete Bridge Rail, Jacob Delone
Development Of A Mash Test Level 4 Open Concrete Bridge Rail, Jacob Delone
Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research
An open concrete bridge rail was designed and developed according to safety performance guidelines in the American Association of State Highway Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) for Test Level 4 (TL-4). Systems designed and developed under previous guidance were studied, and their geometric information and full-scale crash testing performance was studied to establish the geometry of the new bridge rail. Yield-Line Theory and the AASHTO Post and Beam design methods were studied, and a modified version of the AASHTO Post and Beam method was utilized to determine the capacity of the new open concrete bridge rail. …
