Determination of Minimum Height and Lateral Design Load for MASH Test Level 4 Bridge Rails

Description: "This research had the objectives of determining the minimum rail height and lateral design impact load for MASH test level 4 bridge rails. Using parametric finite element analysis and subsequent crash testing, the researchers determined the minimum recommended rail height for MASH TL-4 impact conditions to be 36 inches. Later Design impact for MASH TL-4 test conditions was determined to be 80 kips."
