EXPERIMENTAL STUDY OF PRESTRESSED CONCRETE UNDER COMBINED TORSION, BENDING, AND SHEAR

THE DESIGN AND CONSTRUCTION OF A 159-FT DUAL TRACK RAILWAY BRIDGE THAT WAS BUILT NEAR SYDNEY, AUSTRALIA, USING PRECAST PRESTRESSED CONCRETE SEGMENTAL CONSTRUCTION IS DESCRIBED. THE BRIDGE CONSISTS OF SEVEN SIMPLY SUPPORTED 159-FT SPANS GIVING A TOTAL SPAN LENGTH OF 1113 FT 2 IN. THE SUPERSTRUCTURE IS MADE UP OF TWIN PRECAST POST-TENSIONED BOX GIRDERS. EACH OF THE FOURTEEN 159-FT SPANS IS COMPOSED OF SIX SEGMENTS ABOUT 7 FT WIDE BY 12-1/2 FT DEEP. THE DECK IS FORMED BY CAST-IN-PLACE POST-TENSIONED CANTILEVER SLABS. BECAUSE OF POOR SOIL CONDITIONS, 92 INCLINED COMPOSITE PILES (UP TO 166 FT IN LENGTH) WERE USED TO SUPPORT THE SOUTH ABUTMENT AND PIERS. THE PILES CONSIST OF 12 X 12-IN. STEEL H SECTIONS CONNECTED TO 21-IN. SQUARE PRESTRESSED CONCRETE PILES. THE BID PRICE FOR THE BRIDGE WAS $2.6 MILLION. /AUTHOR/
