| Abstract: | A procedure analyzing geometrical nonlinearity of long-span cable-stayed bridges is proposed considering geometric nonlinear effects based on structural nonlinear finite element equilibrium equation using U.L. formulation. A numerical example is given. The results show that the accuracy of analyzing geometrical nonlinearity of long-span cable-stayed bridges by the presented procedure is validated. The initial cable forces can be well determined. |
