| Abstract: | External pretressing is a kind of active reinforcement technology. According to the typically broken line configuration of external tendon in continuous-beam bridge, dimensionless parameters are used to generalize the deviators＇ positions. Taking the maximum bending moment of key cross-sections as object, the position parameters of external tendon are studied. The efficiency of the proposed method is verified by tendon configuration analyses in a continuous-beam bridge. |

| Keywords: | continuous-beam bridge external prestressing reinforcement tendon configuration design |
