SAFER SIGN AND LUMINAIRE SUPPORTS. TASK L. FINAL REPORT. VOLUME V
The purpose of the study was to determine practical laboratory methods of testing breakaway supports to assure their effectiveness in automobile/support impacts. The study involved analysis and computer simulation of vehicle impacts with breakaway sign and luminaire supports. A pendulum impact test facility was designed and built, and impact teste were conducted on sign and luminaire supports. The results of these laboratory tests incorporating a crushable nose of aluminum honeycomb were compared with full-scale impact tests as well as computer-simulated impacts. Correlations were found to be good for slip base structures, while for shoe base luminaires the scatter was too large to make definite conclusions. The study has resulted in recommendations for minimum sizes for foundations for luminaire supports and the specification of single laboratory test criteria incorporating crush rate parameters.
