AN INTERACTIVE DESIGN ALGORITHM FOR PRESTRESSED CONCRETE GIRDERS

THE ALGORITHM, GUIDED BY THE ENGINEER, SELECTS, FROM TABULATED STANDARD CROSS-SECTIONS AND ASSOCIATED COMBINATIONS OF PRESTRESSING FORCES AND ECCENTRICITIES, THE CROSS-SECTION, PRESTRESSING FORCE, AND ECCENTRICITY TO SATISFY THE PROBLEM CONSTRAINTS. THE KERN BOUNDARIES ARE CALCULATED IN THE ANALYSIS PORTION OF THE ALGORITHM. THE ENGINEER, USING THE KERN BOUNDARIES, DETERMINES THE PATH OF THE STRANDS BY SPECIFYING THE STRAND HOLD-DOWN POINTS AND ASSOCIATED STRAND CENTROID ECCENTRICITY. THE ALGORITHM ALSO PROVIDES FOR SHEAR REINFORCEMENT, DEAD LOAD DEFLECTIONS AT TRANSFER AND AFTER PLACEMENT OF THE SLAB, AND AUXILIARY NONPRESTRESSED TENSION REINFORCEMENT AT TRANSFER.
