NCHRP Report 350 Evaluation of the Nebraska Thrie-Beam Transition

摘要

This project was initiated to develop a thrie-beam transition to a concretebridge rail which is capable of passing the criteria set forth in NCHRP Report 350. The system currently used by the Nebraska Department of Roads was redesigned with the help of the BARRIER VII computer program. This redesigned system was subjected to one test with a 2000-kg pickup impacting the system at 100 km/h and 25 degrees. The vehicle was redirected in a stable and controlled manner, but considerable occupant compartment damage occurred during the impact, resulting in failure of the test.
