| Abstract: | The characteristic of forces acting in the end block anchorage of unbonded prestressed tendons is analysed. Author suggested that the calculation of end block of bearing strength should be taken with two steps: prestressing stage and ultimite limit states. In addition, the constructional details of end block and engineering examples are presented. |
