| Abstract: | In this paper, on the basis of the practice of writing UP program, the significance of optimized computing in design of post stressed concrete structures is discussed. The reasonable combination of both post tensioned tendons and steel bars with the concept of optimized origin in design calculation is presented with correlate factors. After spreading out the basic calculating contents in optimized design of post stressed structures by special program, some new design viewpoints are proposed. |
