Abstract
A method of tensioning parallel prestressing members of a building or building component of prestressed concrete or a tension member composed of a plurality of individual elements, such as steel rods, steel wires or steel strands, wherein the individual elements are successively tensioned either individually or in groups. The tensioning method described above includes the steps of tensioning a first individual element or a group of individual elements until a predetermined tension is reached and anchoring the first individual element or group of individual elements; tensioning a second individual element or a group of individual elements until the tension thereof is equal to the tension of the previously tensioned individual element or elements at the same time and anchoring the second individual element or group of individual elements; and repeating the preceding step until all individual elements are tensioned and anchored.
