EVALUATION OF A PRESTRESSED PANEL, CAST-IN-PLACE CONCRETE BRIDGE

A RELATIVELY NEW TYPE OF BEAM AND SLAB BRIDGE WHICH MAKES USE OF PRECAST, PRESTRESSED PANELS AS PART OF THE SLAB WAS INVESTIGATED. IN THIS TYPE OF BRIDGE CONSTRUCTION, THE PANELS ARE PLACED BETWEEN THE BEAMS TO SERVE AS FORMS FOR THE CAST-IN-PLACE PORTION OF THE DECK. THEY REMAIN IN PLACE TO BECOME AN INTEGRAL PART OF THE CONTINUOUS STRUCTURAL SLAB. COMPOSITE ACTION IS OBTAINED IN THE STRUCTURE BY BONDING THE PRESTRESSED ELEMENTS TOGETHER WITH THE CAST-IN-PLACE PORTION OF THE DECK. THIS TYPE OF STRUCTURE INCORPORATES UNPROVEN STRUCTURAL DETAILS--THE BONDING OF CONCRETE AT THE INTERFACES AND THE INCLUSION OF PANEL BUTT JOINTS. A FULL-SCALE, SIMPLE SPAN, PRESTRESSED PANEL TYPE BRIDGE WAS STRUCTURALLY TESTED IN THE LABORATORY. THE BRIDGE WAS SUBJECTED TO CYCLIC APPLICATIONS OF DESIGN LOADS AND FINALLY TO STATIC FAILURE LOADS. IT PERFORMED SATISFACTORILY UNDER ALL LOAD CONDITIONS. /AUTHOR/
