Dynamic Tests of Five Breakaway Standard Base Designs

摘要

A study to determine the effectiveness of five breakaway lighting standard base designs in reducing the severity of vehicular impacts by means of full scale dynamic tests is reported. Ten head-on tests were conducted utilizing identical 1966 sedans weighing 4,540 lbs. and impacting 30 ft. lighting standards mounted on the various frangible or slip-base designs. All of the poles used in the tests were steel with the exception of one tapered aluminum design. (Author)
