AUTOMATED OPTIMUM DESIGN OF SOME HIGHWAY BRIDGES AND BRIDGE ELEMENTS

During the past 20 years extensive developments in the application of math programming techniques to the automated, optimum design of structures have made it possible to consider the routine design office application of these techniques. The goal of this project was to produce working computer programs which the designer could use easily and effectively. Two quite different problems were approached; the design of continuous rolled beam bridge girders and the design of reinforced concrete slab bridges. A number of different classes of rolled beam bridges were studied. A computer program, GAD III having several options was developed to perform the design of non-composite, continuous rolled beams. The simplest option will select the lightest rolled beam which meets all requirements for the total length of the continuous beam. A second option will design a minimum cost continuous beam with coverplates. Only a single rolled beam section is allowed. A third option allows both coverplates and changes in rolled beam sections. The GAD VI program will design a minimum cost composite beam. Both beam and shear connectors are designed. The Minimum cost design of a continuous reinforced concrete slab bridge is performed by the GAD IV program. A uniform depth slab is used and all reinforcement is designed. All of these programs were written in FORTRAN and have been tested on both the UNIVAC 1108 and the IBM 360. /Author/
