ABSTRACT:
A tie anchor for strip-type tension members includes an anchor body disposed on at least one side of the tension member. The anchor body includes a plurality of clamping blocks arranged at a distance from each other in a longitudinal direction of the tension member. The clamping blocks are connected to tension member by adhesive and/or friction (clamping friction). An end-most (final) one of the clamping blocks is attached to a fixed abutment. Adjacent clamping blocks are interconnected by expansion members whose spring stiffness becomes progressively stronger toward the end-most clamping block.
