THE SHEAR STRENGTH OF PRE-TENSIONED I BEAMS WITH UNREINFORCED WEBS

THE RESULTS OF TWO-POINT LOADING SHEAR TESTS ON 50 PRETENSIONED CONCRETE I BEAMS WITHOUT WEB REINFORCEMENT ARE PRESENTED. ALTHOUGH MANY OF THE BEAMS CARRIED A SHEAR LOAD GREATER THAN THE CRACKING SHEAR LOAD, THE AMOUNT OF THE EXCESS COULD NOT BE PREDICTED. IT IS CONCLUDED THAT FAILURE HAS OCCURRED WHEN THE WEB IS CRACKED IN SHEAR. AN EXPRESSION IS DEVELOPED FOR THE DIAGONAL CRACKING SHEAR FORCE. TEST RESULTS ALREADY PUBLISHED ARE SHOWN TO GIVE SATISFACTORY AGREEMENT WITH THIS EXPRESSION, AND FOR SPECIFIC CASES, COMPARISONS ARE MADE BETWEEN THE ULTIMATE SHEAR LOAD PREDICTED BY IT AND OTHER DESIGN EQUATIONS AND CODE RULES. /AUTHOR/
