Abstract

Road safety barrier is function to absorb the impact during the crash. It also functions to keep the vehicle at safe side of the road. During the crash, there were severity that will be produced, and it will cause some damage to the vehicle and the obstacle. The purpose of this project is to determine the effect of the crash at different angle. To accomplish the objective, the computational aided design (CAD) software will be used to draw 3D geometry modelling. Then, the 3D model, the analysis is conduct at several different angles and 2 type of truck. From the analysis, several results will be obtain and will be used as comparison parameters. The comparison will be done between the angles, type of truck, type of analysis and previuos study. From the static analysis it was found that the critical component of road safety barrier was w – beam guardrail while in dynamic analysis, it was found that the critical component of road safety barrier when velocity applied were guardrail post and spacer channel. It show that the critical component was different for different type of analysis. It also found that the safety factor of road safety barrier that installed at our roadways is less than 1 which for static analysis was 0.26237 and for dynamic analysis was 0.058942. This means that the installation of road safety barrier nowadays was not applicable anymore unless the current design is redesign in order to make it can withstand the impact from a bigger force.
