Abstract
Road-traffic crashes are one of the world’s largest public health and injury prevention problems. Median Barrier such as W-beam Corrugated Guardrail is a barrier on a road designed to prevent vehicles from leaving the roadway to improve road safety. Full-scale impact testing has been and will continue to be the most common method of evaluating the safety performance of guardrails, median barriers and others. The purpose of this research was to develop and evaluate a full-scale computational model of the road safety barrier for use in crash simulations with ABAQUS/ EXPLICIT Software and further compare the computational results with test data. In this present study the behaviour of W-beam guardrail is examined using laboratory specimen tests both statically and dynamically simulated using finite element analysis by analyzing the W-beam Corrugated Guardrail and Solid Car Bumper under crash condition based on NHRCP 350 reports. This is to identify the effects on mechanical properties of W-Beam Corrugated Guardrail and to describe as well the energy absorbing capability of W-Beam Corrugated Guardrail would produce after the crash impact occur.
