Low-Impact, High Toughness Transportation Barriers

Alternatives to existing transportation truck escape ramps and crash barriers are examined using arrays of wood, bamboo, and fiberglass structural elements that act as energy absorbers as they deform. The behaviors of each material type are analyzed to determine if they have the necessary potential for extensive use in such applications. Calculations based upon static and dynamic testing are made to predict the type of system required to bring vehicles to a stop. The findings are discussed and guidelines for future applications are suggested.
