TESTS ON BEAMS WITH REINFORCED WEB OPENINGS

SIXTEEN ELASTIC TESTS AND THREE ULTIMATE LOAD TESTS ON A36 STEEL W12X45 BEAMS WITH REINFORCED RECTANGULAR OPENINGS IN THE WEB AT MIDDEPTH ARE DESCRIBED AND ANALYZED. THE EXPERIMENTAL VARIABLES WERE THE MOMENT-SHEAR RATIO AT THE OPENING AND THE DETAILS OF THE HORIZONTAL REINFORCING BARS WHICH WERE USED ABOVE AND BELOW THE OPENINGS. FILLET WELDS PLACED ON ONLY ONE SIDE OF THE REINFORCING BARS PROVIDED AN ADEQUATE CONNECTION TO THE WEB BOTH FOR ONE AND TWO-SIDED REINFORCING BARS. THE USE OF REINFORCING BARS ON ONLY ONE SIDE OF THE WEB HAD NO INTERPRETABLE EFFECT ON THE STRENGTH AND BEHAVIOR OF THE BEAMS. IT IS CONCLUDED THAT DESIGNING THE EXTENTION OF THE REINFORCING BARS BEYOND THE EDGES OF THE OPENING TO DEVELOP THE STRENGTH OF THE BARS IN THE WELDS IS A REASONABLE AND SATISFACTORY APPROACH TO THIS DETAIL. /AUTHOR/
