Abstract

This project is entitle ‘W-shape Beam Subject to Quasi-static Loading’. Nowadays, most people used main road and expressway for commuting transport. Roadside safety is important to reduce the number of fatalities and serious injuries resulting from run-off-road crashes. W-beam barrier may be the most widely used type of roadside safety hardware. Various methods used to test and improve the efficiency of this hardware. In this project, W-shape barrier material properties and behaviors were obtained by performing the tensile and Rockwell hardness tests. Then, W-shape barrier with 50 mm width was applied with various rate of compression, ranging from 5 mm/min to 30 mm/min to observe the deforming mode. The deforming mode was captured by digital and video cameras. The energy absorbed was calculated by measuring the area under the load-displacement curve obtained from Instron Universal Testing Machine. The W-shape beam absorbed approximately 250 J of energy in 69 mm of permanent deformation.
