| Abstract: | The understandings and supplements are made for theoretical extension value calculation of prestressed reinforcement stretched by means of post-tensioning in the specification for highway bridge and culverts construction. Accurate segment calculation formula is derived for theoretical extension value calculation of curve reinforcement combined with line and curve. In addition the matters needing attention in calculation are presented. |
