• Abstract:
  Portable Concrete Barriers (PCBs) are used to redirect errant vehicles to keep them passing to opposing lanes and to ensure safety of the ; people and any objects behind the barriers. In the state of Indiana, increments to the PCBs, such as L‐Shape steel plates, have been ; applied to enhance the safety performance of these barriers. In this study, Finite Element (FE) analyses are performed to evaluate the ; safety performance of PCBs with and without the increments and get thorough information about the increments applied. A full‐scale ; crash test (INDOT, 2001) was executed for an impact to the PCBs with a 2000 kg pickup truck at an angle of 25 degrees and an initial ; velocity of around 100 km/hr in accordance with National Cooperative Highway Research Program (NCHRP) Report 350 guidelines for ; Test Level 3 safety performance. Aforementioned full‐scale crash test data are used to validate the FE model constructed. Roadside ; Safety Verification and Validation Program (RSVVP) was used to compare the crash test and FE model results quantitatively. Validating ; the results of the initial FE Model leaded the way in confidence to implement the increments in the following FE Models.
