【Abstract】 Formulas for the calculation of effective prestressing force and the set back amount of a loop prestressed cable are derived and used in the calculation of distribution of effective prestressing force and the set back amount of prestressed cables in the anchorage region on the pylon of the E\|Huang Changjiang Highway Bridge. The results show that the formula can accurately give the distribution of effective prestressing force of a loop prestressed cable.更多还原
