CONTINUOUS PRESTRESSED CONCRETE GIRDERS WITH KEYED SCARF CONNECTIONS

A 110-FOOT (33.60 M) LONG CONTINUOUS BEAM, WITH TWO 54-FOOT (16.45 M) SPANS, COMPOSED OF THREE PRECAST PRESTRESSED SEGMENTS AND JOINED NEAR INFLECTIN POINTS BY KEYED SCARF CONNECTIONS, WAS TESTED TO FAILURE. PRESTRESSED KEYS, EPOXYSAND MORTAR CUSHIONING, AND HIGH TENSION BOLTS WERE USED IN THE SPECIALLY DESIGNED SCARF CONNECTIONS. THE BEAM BEHAVED IN ALL RESPECTS AS A MONOLITHIC PRESTRESSED CONTINUOUS BEAM. SERVICE AS WELL AS ULTIMATE LOAD DESIGN CRITERIA ARE ESTABLISHED FOR THE KEYED SCARF CONNECTIONS USED. A NUMERICAL EXAMPLE ILLUSTRATING HOW THE MAIN FINDINGS OF THE PAPER MAY BE APPLIED IN ACTUAL DESIGN IS GIVEN. /AUTHOR/
