| 1. A method for tensioning a staggered anchorage having a plurality of tension members that are anchored in a bore hole and
have different free steel lengths, the method comprising the steps of:
adjusting each tension member to a predetermined maximal load and then subsequently to a working load, and
adjusting all tension members to a reduced elongation by a uniform elongation difference relative to a respective elongation
of the predetermined maximal load to adjust the staggered anchorage to the working load.
