DESIGNING FAIL-SAFE STRUCTURES FOR HIGHWAY SAFETY
HIGHWAY RESEARCH HAS MET, AND IS CONTINUING TO MEET, THE CHALLENGE TO HELP STEM THE ENORMOUS ACCIDENT TOLL OF THE NATION'S HIGHWAY SYSTEM. IN ADDITION TO NUMEROUS INNOVATIONS ON THE ROADWAY ITSELF, REVISIONS TO THE ROADSIDE ARE VIRTUALLY ELIMINATING LETHAL TARGETS AT WHICH ERRANT VEHICLES OFTEN ARE DIRECTED. NOT ONLY ARE ROADSIDE APPURTENANCES BEING PLANNED OUT OF PROBABLE COLLISION ZONES BUT SAFE FAILURES ARE BEING DESIGNED-IN FOR THOSE THAT CANNOT BE RELOCATED FEASIBLY. THESE FAIL-SAFE STRUCTURES, WHICH HAVE NEARLY ELIMINATED FATALITIES AND DRASTICALLY REDUCED INJURY AND PROPERTY DAMAGE AT LOCATIONS WHERE THEY HAVE REPLACED RIGID STRUCTURES, ARE BEING IMPLEMENTED EACH MONTH BY STATE HIGHWAY DEPARTMENTS. FAIL-SAFE STRUCTURES MUST BE DESIGNED FOR BOTH STRENGTH TO PERFORM THE TASKS FOR WHICH THEY WERE BUILT, AND WEAKNESS TO YIELD UNDER IMPACT. SOME OF THE DESIGNS THAT INCORPORATE THESE SEEMINGLY INCOMPATIBLE CHARACTERISTICS ARE REVIEWED, SOME OF THE PROBLEMS ENCOUNTERED IN FAIL-SAFE STRUCTURE DESIGN, DISCUSSED. /AUTHOR/
