A number of studies, by the author and others, have shown that the Limit State Design method can, when applied to the design of bridge superstructures, produce more rational and economic designs than conventional methods. Most studies have been made on the assumption that the basic structural layout, proportioning, and material characteristics would be determined by the rules used for conventional design. The authors have pointed out that these rules are possibly no longer applicable and that greater economies could be obtained by some form of optimization procedure. This paper describes the application of Geometric Programming to the solution of such a problem. It is shown that excellent results can be obtained with a simplified version of the technique in which the “degree of difficulty” is reduced to zero. The superiority of Geometric Programming as an optimum design technique is demonstrated by comparing the results for the example chosen with those obtained by alternative methods. |
