Abstract
A dynamic analysis approach for nonlinear cable and cable-stayed structures is presented by minimizing the total potential dynamic work. Three time-integration methods for nonlinear dynamic analysis are described. These are the linear change of acceleration method, the Wilson-θ method and the Newmark method. Mathematical expressions for the gradient of the total potential dynamic work are developed together with the minimization of the total potential dynamic work using the conjugate gradient method. The magnitude of the time step, the convergence and scaling are discussed, followed by a numerical example.
