Abstract

The paper presents a method for modeling cables for analyzing the given design deck profiles of cable stayed bridges. A linearized equilibrium equation of a cable element, which includes the cable element stiffness matrix and internal force vector, is formulated using the analytical solution of an elastic catenary cable. The reliability and efficiency of the proposed method are demontrated through a numerical sample. Only procedures to model cables are presented in detail. Frame elements using for modeling deck and pylons can be inferred to be known or referred to finite element method books.
