THE ULTIMATE LOAD CAPACITY OF BEAM AND SLAB BRIDGES

THEORETICAL STUDIES AND MODEL TESTS OF TWO AND FOUR- GIRDER BEAM-AND-SLAB BRIDGES OF REINFORCED CONCRETE ARE BRIEFLY DESCRIBED. THE ULTIMATE LOAD CAPACITY MAY BE ESTIMATED CLOSELY BY LIMIT AND ULTIMATE STRENGTH DESIGN PROCEDURES PROVIDED DUE ATTENTION IS GIVEN TO SHEAR-TORSION INTERACTION IN THE BEAMS. THE USEFULNESS OF INTERIOR DIAPHRAGMS IS QUESTIONED. THE CONTRIBUTION OF THE SLAB TOWARDS ULTIMATE STRENGTH MAY BE SIGNIFICANT. THE RESULTS OF SOME OPTIMIZATION (LEAST WEIGHT) AND LEAST COST STUDIES OF BEAM AND GIRDER BRIDGES OF SPANS 50 TO 80 FT. ARE PRESENTED. /CGRA/
