Determining Lateral Deflections of Plastic Water-Filled Barriers

MB42x72 JSS LCD with fencing at SD Ballpark

This study investigated two methods that can be used to calculate the lateral deflection and the number of segments that move in a PWB after a vehicle has struck the traffic barrier. In the first method, theoretical equations were developed based on the conservation of energy. The second method used MADYMO simulations to calculate how the barrier deformed.The theoretical equations and the MADYMO simulation models developed in this study were validated against full-scale crash tests.
