Abstract
The possible deleterious effects of coiling and long time storage of coiled wires on the stress relaxation behaviour of prestressing steel wires has been checked by means of experimental work and a simple analytical model. The results show that if the requirements of Standards are fulfilled (minimum coiling diameters) these effects can be neglected. However, some other factors like previous residual stresses, long time storage or storage at high temperatures, can trigger or emphasize this damage on the material. In the authors? opinion it is recommended to control the final curvature of the wires after uncoiling prior to prestressin, as required in some Standards.
