| Abstract: | Based on the analysis of disadvantages of traditional design method,a new optimization method based on neural network is proposed.Making use of the stepped reduction method by Yah.the flexural rigidity optimal distribution of the equi-strength static-indeterminant beam under a concentrated force is studied in this paper.The governing equation can be explicitly expressed by the design variable as well as geometry constraint. |

| Keywords: | neural network simulated annealing algorithm static-indeterminant beam optimization design |
