DYNAMIC TESTING OF LUMINAIRE SUPPORTS WITH AN IMPROVED PENDULUM IMPACT FACILITY

The report presents the results of a staff study leading to the development of a validated pendulum substitute for the full scale tests of luminaire supports as required by current AASHTO specifications. The resulting pendulum test procedure adequately simulated a 20 mph full-scale head on test with pre 1973 Vega in terms of change of momentum, structural deformation, impact duration, peak loads, and failure modes. As a byproduct of this effort, added insight has been obtained on pendulum and target structure parameters that may be critical in affecting the momentum transfer of the impacting vehicle. /FHWA/
