Impact Tests of Luminaire Supports with the 1800-lb. Pendulum

摘要

The report contains the results of the crash tests performed with the 1800-lb (817.2-kg) pendulum on slip base and anchor base luminaire supports. Also contained in this report are the results of tests performed on a breakaway sweeper plate which was attached to the underside of the pendulum body and should more accurately represent the undercarrage of an automobile. The luminaire supports were tested at a speed of 20 mi/h (8.94 m/s). These devices were previously tested at the Federal Outdoor Impact Laboratory (FOIL) with the breakaway bogie vehicle. The results of the bogie tests are presented in FHWA reports FHWA-RD-88-253 and FHWA-RD-88-258. The anchor base luminaire support has since been modified with a groove to allow the device to break away with a lower stub height. The results of these tests are presented in FHWA-RD-90-056.
