| Abstract: | The formula of the prestress loss due to friction of the prestressing tendon is only fit for a plane curve in the present codes,not fit for the spatial curves.A formula to calculate the prestress loss due to friction of the prestressing tendon with a spatial curves is proposed in the paper. |
