摘要
It is difficult to calculate the flexible cable because of highly geometrically nonlinear behavior. However, the cable equilibrium configuration of cable supported bridges influents bridge construction. Cable curve equation in Lagrangian coordinate is proposed in the paper. Then, the two node nonlinear cable element tangent stiffness matrix is derived and its iterative step is given. The reliability of the method is verified by studying the cable configuration and the unstressed length. The results are agreed with analytic solution.
