DESIGN OF SLIP BASES FOR BREAKAWAY SIGNS

THE OBJECT OF THE STUDY WAS THE DESIGN OF ECONOMICAL SLIP BASES FOR BREAKAWAY SIGN SUPPORTS. THE STYLE OF BASEPLATE PREVIOUSLY USED IN KANSAS, ALTHOUGH MOST ECONOMICAL TO FABRICATE, WAS TOO HEAVY BECAUSE THE BASEPLATE THICKNESS HAD BEEN BASED ON A THEORETICAL ANALYSIS THAT CONTAINED SEVERAL CONSERVATIVE ASSUMPTIONS. THEREFORE, FULL-SCALE TESTS WERE RUN USING EXPERIMENTAL STRESS ANALYSIS TECHNIQUES TO DETERMINE A MORE ACCURATE ANALYSIS METHODS. A DESIGN METHOD WAS DEVELOPED BASED ON THESE RESULTS. APPLICATION OF THE METHOD ALLOWS THE USE OF FLAT BASEPLATES THAT MEET THE MAXIMUM WEIGHT RECOMMENDATIONS SET FORTH BY THE TEXAS TRANSPORTATION INSTITUTE. THIS IS ESTIMATED TO RESULT IN AN ANNUAL SAVINGS OF $20,000 IN KANSAS. /AUTHOR/
