prestressingkabels
Prestressingkabels, or prestressing cables, are high-strength steel tendons used to introduce compressive stresses into concrete members. By applying an initial pretension, these cables counteract tensile forces generated during service, reducing crack formation and minimizing deflections. They are central to the construction of prestressed concrete elements such as beams, slabs, and bridges.
Most prestressingkabels consist of strands or wires made from high-strength steel. Common forms include seven-wire strands,
Pretensioning involves tensioning cables against fixed end supports prior to concrete placement, then releasing the anchors
Design must account for long-term losses from relaxation, concrete creep and shrinkage, friction between tendons and
