ANALYSIS OF CONTINUOUS COMPOSITE BEAMS
A METHOD OF ANALYSIS WAS DEVELOPED FOR CONTINUOUS COMPOSITE BEAMS WITH INCOMPLETE INTERACTION. THE METHOD IS GENERAL AND CAN BE USED FOR ANY CONTINUOUS COMPOSITE BEAM SYSTEM. THE ANALYSIS MAY INCLUDE THE ELASTIC AND INELASTIC BEHAVIOR OF ALL ELEMENTS OF THE CONTINUOUS COMPOSITE BEAM, AS WELL AS THE EFFECT OF SHRINKAGE AND A PRESTRESSING FORCE IN THE CONCRETE SLAB. THE THEORETICAL RESULTS WERE COMPARED WITH THE EXPERIMENTAL RESULTS OF LABORATORY TESTS ON CONTINUOUS BEAMS. SATISFACTORY CORRELATION WAS OBTAINED BETWEEN THE ANALYSIS AND THE EXPERIMENTAL VALUES OF SLAB FORCE, SHEAR CONNECTOR LOADS AND STRAIN DISTRIBUTION IN THE CROSS-SECTION. RECOMMENDATION FOR THE NUMBER AND SPACING OF SHEAR CONNECTORS, AND THE AMOUNT AND ARRANGEMENT OF THE LONGITUDINAL REINFORCING STEEL IN THE NEGATIVE MOMENT REGION OF CONTINUOUS COMPOSITE BRIDGES ARE MAD. /AUTHOR/
