COMPOSITE BEAMS WITH STUD SHEAR CONNECTORS
TESTING OF A COMPOSITE BEAM STRUCTURE CONSISTING OF A 6-IN. DECK SLAB 32 FT. LONG AND 10 FT. 11 IN. WIDE AND TWO 18WF50 BEAMS 32 FT LONG IS DESCRIBED. THE SHEAR CONNECTORS ON ONE OF THE BEAMS WERE 3/4-IN. DIAMETER STUDS WITH UPSET HEADS, WELDED TO THE TOP FLANGE. ON THE OTHER BEAM, 1/2-IN. DIAMETER STUDS WITH END HOOKS AT RIGHT ANGLE WERE USED. THE LOADING PROGRAM CONSISTED OF 1 MILLION CYCLES AT 100 PERCENT, AN ADDITIONAL 250,000 AT 125 PERCENT, AND A FURTHER 250,000 AT 150 PERCENT OF THE DESIGN LIVE LOAD. FINAL FAILURE WAS PRODUCED BY STATIC LOADING. BOTH TYPES OF SHEAR CONNECTORS BEHAVED SATISFACTORILY UNDER ALL TESTING CONDITIONS. ON THE BASIS OF THESE EXPERIMENTAL RESULTS TENTATIVE DESIGN RECOMMENDATIONS CONCERNING THE USE OF STUD SHEAR CONNECTORS ARE MADE. THE DESIRABILITY OF FURTHER EXPERIMENTAL STUDIES IS INDICATED, LEADING ULTIMATELY TO LESS CONSERVATIVE DESIGN RULES. /AUTHOR/
