A REPORT ON BRIDGE GIRDER WEBS SUBJECTED TO HORIZONTAL LOADS

IN CONSTRUCTION OF PLATE GIRDERS, WHEN NO GROUND SUPPORTED FALSEWORK IS USED, METAL BRACKETS BOLTED TO THE WEB OF THE EXTERIOR GIRDERS ARE USED TO SUPPORT CONSTRUCTION LOADS. THE OBJECTIVE OF THIS STUDY WAS TO INVESTIGATE THE WEB STRESSES AND DEFLECTIONS WHICH OCCUR AS A RESULT OF USING TEMPORARY CONSTRUCTION BRACKETS. FOUR BRACKET TYPES WERE STUDIED EXPERIMENTALLY UNDER IDEAL CONDITIONS; A MATHEMATICAL SOLUTION WAS ESTABLISHED FOR A SIMPLIFIED BRACKET TO PREDICT THE STRUCTURAL BEHAVIOR OF THE WEB UNDER LATERAL LOADS; AND FINALLY, WEB STRESSES AND DEFLECTIONS DUE TO TEMPORARY BRACKET LOADS WERE DETERMINED FOR AN ACTUAL BRIDGE UNDER CONSTRUCTION. SUCH STRESSES WERE COMPARED WITH LABORATORY TESTS TO AID IN ACCURATELY DETERMINING THE BEHAVIOR OF A GIRDER WEB WHEN SUBJECTED TO HORIZONTAL LOADING. /AUTHOR/
