TENDON ANCHORAGE AND CONSTRUCTION METHOD OF A PRE-STRESSED CONCRETE STRUCTURE
An anchorage includes a bearing plate arranged in an end portion of a concrete structure with an insertion hole formed therein and formed with a through hole connecting to the insertion hole. A sleeve is inserted through the insertion hole and the through hole, with one end portion of the sleeve disposed on the outside of the structure. A tendon is inserted within the sleeve, with one end portion of the tendon disposed on the outside of the structure. A locknut is engaged with the one end portion of the sleeve and in contact with the outer surface of the bearing plate. A PC grout fills the insertion hole and the sleeve. Before filling, the tendon is applied with tension and, after strength expression of the PC grout, the tension is released. The tendon undergoes a Poisson effect to expand radially outward and compression stress occurs in the PC grout.
