abstract="In this study, a bridge rail-to-guardrail transition is analysed to fully evaluate its crashworthiness. A non-linear, large-deformation finite-element simulation programme LS-DYNA is used for the analysis. Previous studies have predicted that the transition was able to successfully contain and redirect a 2000 kg pickup truck under National Cooperative Highway Research Program (NCHRP) Report 350 test level 3 conditions. In this study, the transition was subjected to an 8000 kg single-unit truck impact according to NCHRP Report 350 test level 4 conditions. Both the model of the 8000 kg truck and the transition structure used in this study were acquired from previous successful studies. <br><br>RESULTS of the simulation study showed that the transition structure was found to be adequate in containing and redirecting an 8000 kg truck. It was also determined that the post-impact trajectory of the truck, occupant risk values, article deflections and exit conditions were very similar to those obtained from a similar transition structure previously crash-tested under test level 4 conditions. It was concluded that the finite-element model of the vertical flared-back bridge rail-to-guardrail transition is fairly accurate and can be used in further studies, such as the MASH test level 4 crash simulation with confidence.<p /> <p>Language: en</p>",
