USE OF EPOXY COMPOUNDS AS A SHEAR CONNECTOR IN COMPOSITE T-BEAMS
THREE HIGHWAY DEPARTMENTS, TWO AT OPPOSITE BOUNDARIES OF THE CONTINENTAL UNITED STATES, INDEPENDENTLY GAVE CONSIDERATION TO THE PROPOSED USE OF EPOXY RESIN COMPOUNDS AS A SHEAR CONNECTOR. THE POSSIBLE BENEFITS TO BE GAINED BY THIS TYPE OF CONSTRUCTION INCLUDE THE FOLLOWING' /1/ REDUCTION OF BRIDGE DECK CRACKING, /2/ PROVISION OF A CONTINUOUS CONNECTOR, /3/ ELIMINATION OF CONSTRUCTION HAZARDS, AND /4/ ECONOMY. AN EPOXY RESIN COMPOUND CAN SERVE AS A RELIABLE AND SAFE SHEAR CONNECTOR FOR COMPOSITE T-BEAMS. THE EPOXY RESIN FORMULATION AND METHOD OF APPLYING THIS FORMULATION IS DESCRIBED. TEST RESULTS INDICATE THAT VERY SUCCESSFUL BEHAVIOR OF THESE EPOXY-JOINED T-BEAMS CAN BE EXPECTED UNDER LONG-TERM LOADING, EITHER STATIC OR DYNAMIC. THE SHEAR STRESS IN THE EPOXY JOINT IS A PRIME CONSIDERATION WHEN DESIGNING THE T-BEAM. FURTHER WORK LEADING TO DESIGN CRITERIA IS RECOMMENDED.
