Geometrical nonlinearities on the static analysis of highly flexible steel cabl...
Freire, A. M. S.; Negrão, J. H. O.; Lopes, A. V.An evaluation of the importance of geometrically nonlinear effects on the structural static analysis of steel cable-stayed bridges is presented. A finite element model is analyzed using linear, pseudo-linear and nonlinear methods. The pseudo-linear approach is based on the modified elastic modulus. The nonlinear analysis involves cable sag, large displacement and beam-column effects. The results confirm that bo...
