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 emphasise this damage to the material. In the authors’ opinion it is recommendable to control the final curvature of the wires after uncoiling prior to prestressing, as required in some Standards.engAttribution-NonCommercial-NoDerivs 3.0 Spainhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Stress relaxationPrestressing steelCoiling diameterinfo:eu-repo/semantics/conferenceObject691.7info:eu-repo/semantics/openAccess
