Abstract

The minimization method and structural optimization approach used in the SPGBROD program for the optimization of continuous steel plate girder highway bridges are briefly described. The standard optimal design formulation used in the program in discussed. An expression for the maximum deflection of continuous highway bridges is derived in order to form an appropriate deflection constraint equation. The results of some applications of the SPGBROD program are presented.
