STATIC BEHAVIOR OF COMPOSITE BEAMS WITH VARIABLE LOAD POSITION

THE REPORT PRESENTS THE RESULTS OF STATIC TESTS ON TWO IDENTICAL COMPOSITE STEEL-CONCRETE BEAMS. EACH BEAM HAD A SPAN OF 25 FEET AND CONSISTED OF A 60-IN. WIDE BY 6-IN. REINFORCED CONCRETE SLAB CONNECTED TO A 21WF62 A36 STEEL BEAM WITH 3/4 INCH DIAMETER BY 4-IN. HIGH HEADED STEEL STUD SHEAR CONNECTORS. ONE BEAM WAS LOADED AT MIDSPAN TO ITS ULTIMATE LOAD. THE ULTIMATE LOAD WAS THEN APPLIED AT FIVE CONSECUTIVE POSITIONS BETWEEN THE SUPPORT AND MIDSPAN TO SIMULATE A SINGLE CONCENTRATED MOVING LOAD ON THE SECOND BEAM. FROM THE RESULTS OF THE TESTS IT WAS CONCLUDED THAT SUCH COMPOSITE BEAMS DESIGNED IN ACCORDANCE WITH STATIC FLEXURAL STRENGTH REQUIREMENTS WILL BE ABLE TO DEVELOP THE ULTIMATE FLEXURAL STRENGTH AS THE LOAD PASSES ACROSS THE BEAM FROM THE SUPPORT TO THE POSITION OF MAXIMUM MOMENT. /AUTHOR/
