The objective of this project was to develop a stiffened thrie-beam system, which could be implemented in close proximity to fixed objects. In pursuit of this goal, the research team performed numerous computer simulations to determine the minimum required offset to limit the interaction between an impacting vehicle and the fixed object. The researcher team developed both half-post spacing and quarter-post spacing alternative systems with a 75-inch gap between posts through computer simulations. The critical alternative, the quarter-post spacing system with 75-inch gap, was evaluated through physical crash testing. This system successfully met MASH evaluation criteria for tests 3-11 and 3-10. With positive correlation between the computer simulation and physical crash testing, the research team concluded both the quarter-post spacing and half-post spacing alternatives were suitable for implementation on the roadside. Lastly, the research team recommended a transition option for connecting the stiffened systems developed in this project to standard MGS.
