A PROCEDURE FOR THE DETERMINATION OF DESIGN REQUIREMENTS IN CONTINUOUS SKEWED SLAB BRIDGE DECKS

THIS REPORT PRESENTS A METHOD FOR DETERMINING THE MAXIMUM AND MINIMUM MOMENTS IN A THREE-SPAN CONTINOUS SKEWED SLAB BRIDGE DECK UNDER SINGLE VEHICLE LOADING. INFLUENCE CO- EFFICIENTS FOR REGULARLY-SPACED POINTS OF LOAD APPLICATION, WHICH WERE DEVELOPED IN A PREVIOUS STUDY, ARE USED FOR DETERMINING THE MOMENTS AT SPECIFIED NODE POINTS UNDER A PARTICULAR LOADING. A COMPUTER PROGRAM FOR USE WITH THE IBM 1410 WAS DEVELOPED TO CARRY OUT THE PROCEDURE IN COMBINATION WITH A LIBRARY OF INFLUENCE COEFFICIENT SETS FOR A VARIETY OF SYMMETRICAL THREE-SPAN STRUCTURES OF DIFFERENT ANGLE OF SKEW AND WIDTH TO CENTER-SPAN RATIOS FOR PRIMARY INPUT. A VALUE OF 0.8 FOR END TO CENTER-SPAN RATIO IS ASSUMED FOR ALL STRUCTURES. THE ANGLE OF TRANSVERSE REINFORCEMENT AND THE VEHICLE WEIGHT AND AXLE SPACING ARE TREATED AS VARIABLES /BPR/
