IMPACT-YIELDING SIGN SUPPORTS
THE RESULTS OF AN INVESTIGATION OF THE STEEL-CHANNEL SIGN SUPPORTS CURRENTLY USED BY OHIO AND MANY OTHER STATES ARE PRESENTED. THESE STEEL SUPPORTS WHEN STRUCK BY AN AUTOMOBILE WERE FOUND TO YIELD AT THE GROUND LINE, AND THE IMPACTING VEHICLES SHOWED DECELERATION VALUES WELL WITHIN HUMAN TOLERANCE LEVELS. THE STUDY INCLUDED A LABORATORY SIMULATION OF THE CRASH TESTS, A COMPUTER PROGRAM TO EXTRAPOLATE THE RESULTS, AND A FULL-SCALE FIELD TESTING PROGRAM. THE FIELD TESTING PROGRAM INCLUDED 40 CRASH TESTS WITH VELOCITY, SIGN TYPE, ANGLE-OF-COLLISION INCIDENCE, AND SOIL-SUPPORT CONDITIONS AS THE VARIABLES. /AUTHOR/
