Summary

In this paper, the creep of steel spiral strands subjected to constant axial loads is studied both experimentally and numerically. Results of creep tests of spiral strands are presented and discussed. The principal aim of this contribution is to define and describe a design computational tool for numerical simulation and prediction of creep strains of spiral strands. For this purpose, finite element models are developed to simulate creep behaviour of spiral strands. The models are established and calibrated on the basis of experimentally obtained data measured on the strands and on single wires. The creep constitutive equations of wires at different stresses and clearances between wire layers are incorporated into the finite element model for the simulation of creep response of spiral strands. Creep strains of strands with a construction of 1x7 and 1x19 round wires subjected to tension loads are investigated using the finite element software ANSYS and compared with the available results obtained experimentally from creep tests. Three-dimensional beam elements are applied for modelling of wires in the strands. In principle, the required functionality and performance have been implemented in the software and a good agreement with test results has been obtained.
