Impact Severity is important parameter to design concrete barrier in South Korea. However, maximum load and load-time history graph showed different depending on parameters under vehicle impact loading. Therefore, in this study, analysis according was conducted to various impact conditions such as vehicle mass and impact velocity under same impact severity. Obtained results from load-time history graph showed key parameter is velocity compared to vehicle mass.
