OVERHEAD BOX BEAM SIGN

THE RESULTS OF FULL SCALE TESTS ON CANTILEVERED BOX BEAM SIGNS ARE ANALYZED. A TOTAL OF FOUR TESTS WERE MADE, TWO EACH ON AN ALUMINUM STRUCTURE AND A STEEL STRUCTURE. THE STRUCTURES WERE OF THE "BALANCED BUTTERFLY" TYPE, BUT THE CANTILEVERED ARMS WERE TESTED SEPARATELY. ONE ARM USED PLUG-WELD WEB CONNECTIONS AND THE OTHER USED HUCKBOLT FASTENERS. OF PARTICULAR CONCERN WAS THE RESPONSE OF THE 16- GAGE RIBBED SHEET METAL WEB PANELS TO DIRECT SHEAR. TEST MEASUREMENTS ARE COMPARED WITH THEORETICAL VALUES WHEREVER POSSIBLE AND SOME DESIGN CRITERIA ARE RECOMMENDED. /AUTHOR/
