Evaluation and Redesign of Culvert Guardrail and Transition System
The crash performance of a popular guardrail and guardrail transition system used in Ohio was evaluated based on crash procedures outlined in NCHRP Report 350 for test level 3 (TL-3). Finite element analyses of the guardrail and transition system were performed using the LS-DYNA finite element software to simulate NCHRP Report 350 Test 3-10 and Test 3-11 impact scenarios. The results indicated that the original ODOT GR-2.2 guardrail would successfully meet all NCHRP Report 350 test level 3 safety criteria. There were some concerns about compatibility of the guardrail and the transition system. It was shown in the study that the performance of the system could be significantly improved with simple modifications to the guardrail. Based on the results of this study, the original guardrail design and several improved designs were accepted by the FHWA as NCHRP Report 350 TL-3 systems and may be used on the National Highway System at the state’s discretion.
