“…Until now, nonlinear analysis procedures have been developed for shape finding problems of cable bridges: the trial-and-error method [12], the initial force method [10,13], the analytical and iteration method [14,15], the target configuration under dead loads (TCUD) related methods [9], the optimization method [16,17], and the combined method [18].…”

Featured Application: An improved analytical algorithm has been successfully applied in shape finding during design and configuration control during construction of main cable system for suspension bridges.Abstract: This paper develops an improved analytical algorithm on the main cable system of suspension bridge. A catenary cable element is presented for the nonlinear analysis on main cable system that is subjected to static loadings. The tangent stiffness matrix and internal force vector of the element are derived explicitly based on the exact analytical expressions of elastic catenary. Self-weight of the cables can be directly considered without any approximations. The effect of pre-tension of cable is also included in the element formulation. A search algorithm with the penalty factor is introduced to identify the initial components for convergence with high precision and fast speed. Numerical examples are presented and discussed to illustrate the accuracy and efficiency of the proposed analytical algorithm.

Because of the many advances and development in bridge analysis and design, particularly in the area of numerical modelling and computer analysis that have occurred since the advent of the digital computer, previously considered challenging and increasingly more complex highway bridges are now regularly built around the world. These advances oupled with the development of increasingly powerful computers and the fast reducing cost of computing will have significant influence on the future practice of bridge engineering, and also structural engineering in general. This paper presents an overview of some of these developments and the recent trends in bridge modelling and analysis.
