P.C. CANTILEVER ERECTION METHOD USING PRECAST UNITS

THE P. C. CANTILEVER ERECTION METHOD USING PRECAST BOX- TYPE GIRDERS AND EPOXY RESIN INTO JOINTS IS CONSIDERED FOR THE ENGINEERING OF PRESTRESSED CONCRETE. THIS METHOD WAS USED IN JAPAN FOR THE CONTINUOUS EXPRESSWAY VIADUCT WORK WHERE THE TOKYO METROPOLITAN EXPRESSWAY CROSSES OVER RADIAL ROUTE 3. RESULTS ARE DESCRIBED OF TESTS CARRIED OUT ON SPECIMEN TO OBTAIN NEEDED DESIGN DATA, AND THE RESULTS OF EXPERIMENTS EXECUTED ON ACTUAL BRIDGE, AS WELL AS SEVERAL TECHNICAL PROBLEMS OF THE METHOD. THIS METHOD IS APPLIED SINCE: (1) THE ERECTION PERIOD CAN BE SHORTENED BECAUSE THE PRECAST BLOCKS ARE MANUFACTURED WHEN SUBSTRUCTURE WORKS ARE GOING ON, (2) THE QUALITY VARIANCE OF EACH UNIT IS LESS BECAUSE SUFFICIENT CONTROL CAN BE PERFORMED IN THE PRODUCING YARD, (3) ALMOST NO DEFORMATION, DUE TO DAY SHRINKAGE AND CREEP OF CONCRETE, IS OBSERVED BECAUSE THE CURING PERIOD BETWEEN PRECASTING AND PRESTRESSING IS LONG ENOUGH, AND (4) NO TIMBERING IS NEEDED BECAUSE OF SIMPLE ERECTING APPARATUS. /AUTHOR/
