DEVELOPMENT OF A COLLAPSING RING BRIDGE RAILING SYSTEM

An experimental program was conducted to develop an energy-absorbing bridge rail system which used the deformation of steel rings as the primary energy absorber. Fourteen full-scale vehicle crash tests were performed with 2,000-lb, 4,000-lb, 19,000-lb, 40,000-lb and 70,000-lb vehicles. Strain gage, vehicle accelerometer and high-speed movie data were taken.
