| Abstract: | Based on the updated total Lagrangian formulation gcomctric nonlinear analysis of cablc network structures is made with lincar bar clcmant in this paper. Numerical examples show that the incremental method presented in this paper has less calculations, can be used in complicated cable network structures and has satisfactory accuracy for short cable elements. |
