| Abstract: | The formula for accurate calculation on the theoretical value of elongation for the post-tensioning prestressing steel has been derived from the principle of prestress losses due to friction.As a result,it can improve considerably the accuracy of calculation on it in the way of the Technical Specifications for Construction of Highway Bridges and Culverts(JTJ041-2000),thus to provide an important theoretical basis for carrying out the accurate,reliable calculation on prestressing forces. |
