FORCES DUE TO TRAFFIC LOADS ON THE SHEAR CONNECTORS SIMPLY SUPPORTED COMPOSITE BRIDGES
THE LOADS DUE TO TRAFFIC ACTING ON THE SHEAR CONNECTORS OF COMPOSITE BRIDGES (CONCRETE SLAB ON STEEL I-BEAM) WERE EVALUATED MAKING USE OF NEWMARK'S PARTIAL INTERACTION THEORY. A NUMBER OF EXAMPLES WERE WORKED OUT FOR A 32 FT. SPAN SIMPLY SUPPORTED BRIDGE LOADED BY THE PASSAGE OF A VEHICLE REPRESENTATIVE OF THE HEAVIEST TYPE PERMITTED UNDER THE CONSTRUCTION AND USE REGULATIONS. THE CALCULATIONS WERE CARRIED OUT FOR VARIOUS DEGRESS OF CONNECTOR STIFFNESS FOUND IN PRACTICE. AS THE AMOUNT OF INTERACTION IS DECREASED, THE LOADS ACTING ON THE SHEAR CONNECTORS ARE REDUCED. THE STIFFEST SHEAR CONNECTIONS LEAD TO REDUCTIONS OF 10%, 14% AND 22% IN SHEAR RANGES ACTING ON CONNECTORS LOCATED AT THE END, QUARTER-SPAN, AND MIDSPAN SECTIONS RESPECTIVELY. THE MOST FLEXIGLE SHEAR CONNECTIONS LEAD TO CORRESPONDING REDUCTIONS OF 23%, 31% AND 41%. /AUTHOR/
