TEST OF A MODEL THROUGH - VOIDED BOX BEAM BRIDGE

THE RESULTS ARE PRESENTED OF A STATIC LOAD TEST ON A LABORATORY MODEL BRIDGE, COMPOSED OF 4 ADJACENT PRESTRESSED CONCRETE 17" X 36" X 40' BEAMS. TEST CONDITIONS WERE: (1) ISOLATED BEAM TESTS, (2) BRIDGE TEST BEFORE GROUTING OF SHEAR KEYS, WITH AND WITHOUT TIE RODS, (3) AFTER GROUTING OF SHEAR KEYS, WITH AND WITHOUT TIE RODS, AND (4) AFTER CASTING OF COMPOSITE SLAB, WITH AND WITHOUT TIE RODS. RESULTS OF THE TESTS WERE AS FOLLOWS: (1) TIE ROD FORCES WERE ALWAYS SMALL AND THE TIE RODS WERE NOT EFFECTIVE IN LOAD DISTRIBUTION. (2) SHEAR KEYS AND THE COMPOSITE SLAB WERE VERY EFFECTIVE IN LATERAL LOAD DISTRIBUTION. /FHWA/
