DESIGN SENSITIVITY STUDIES ON SIMPLE SPAN PRESTRESSED CONCRETE BEAM AND SLAB HIGHWAY BRIDGE SUPERSTRUCTURES

The results of a set of parametric studies on straight, simple span prestressed concrete beam and slab highway bridges are presented as tabulated information for design. The basic data on design parameters and unit costs are typical of current practice and cover a range of spans and all four beam types. Different parameters are then varied, one at a time, and the consequences on cost and on key structural sizes are determined. Proposed metric sections are also studied and key cross-sectional dimensions are varied to indicate where improvements might be made. /Author/TRRL/
