CONTINUOUS PRECAST PRESTRESSED CONCRETE BRIDGE STRINGERS

A METHOD OF STANDARDIZING THE DESIGN OF PRECAST BRIDGE STRINGERS IS PRESENTED ALONG WITH THEORETICAL DESIGN AND CONSTRUCTION PROCEDURES FOR DEVELOPING CONTINUITY IN MULTISPAN PRECAST PRESTRESSED CONCRETE BRIDGES. EMPHASIS HAS BEEN PLACED ON THE IMPORTANCE OF STANDARDIZING THE DESIGN OF PRECAST CONCRETE UNITS TO REDUCE FABRICATION COST AND IN- CREASE PRODUCT QUALITY. CURRENT PRACTICE OF THE ILLINOIS DIVISION OF HIGHWAYS FOR DEVELOPING CONTINUITY IN MULTISPAN BRIDGES IS DESCRIBED. THE DESIGN INCORPORATES MILD STEEL REINFORCEMENT IN THE BRIDGE DECK, STEEL DOWEL BARS AND A CONCRETE DIAPHRAGM BETWEEN STRINGERS. ADDITIONAL METHODS THAT HAVE BEEN STUDIED INCLUDE POST-TENSIONING AND MECHANICAL STEEL CONNECTING PLATES. /RRL/A/
