Summary

The stiffness of cable structures is conditioned by their states of pre-stress. The decrease of pre-stress arising from creep of cables determines the serviceability and load bearing capacity of the structure. In this paper, a modified force density method and dynamic relaxation method for a time-dependent non-linear static analysis of pre-stressed cable nets and cable domes based on the application of creep theory are presented. Creep constitutive equations are directly used for the adjustment of cable lengths. The accuracy and efficiency of the formulations are assessed by comparison with available results obtained by other authors using different numerical approaches. The applicability of these methods is demonstrated.
