Experimental and computational testing of road safety barriers
One of the major tasks in road transportation is to assure an adequate safety level for road users. To maintain and improve road safety, it is often necessary to install certain devices on the road that are intended to restrain vehicles and pedestrians from entering dangerous areas. The road safety barriers, designed according to the European standard EN 1317, provide certain levels of vehicle containment, properly redirect errant vehicles back on the road and provide guidance for pedestrians and other road users. The presentation focuses on development of full-scale computational models for simulations of crash tests mandated by the EN 1317. The impact severity and stiffness of safety barriers was determined with computational simulations using the explicit dynamic nonlinear finite element code LS-DYNA. Additionally, full-scale crash tests were performed and the measured experimental data were compared with the computational results. From the result a very good agreement between the experimental and computational tests can be observed, which validates and justifies the use of computational simulations for further development of road safety barriers.
