This paper describes ongoing research into the computational aspects of cable stayed bridge analyses. Algorithms have been developed which perform the following design considerations for three-dimensional cable stayed bridges: static analysis with nonlinear effects due to cable sag, axial-flexural interaction, and large displacements; extraction of natural modes for the undeformed and/or deformed service load configuration; and determination of the lowest wind velocity that initiates aerodynamic damping and stiffness driven flutter. All algorithms have been integrated into a graphics based Computer Aided Design (CAD) system residing in a microcomputing environment. Auxiliary programs for mesh generation and bandwidth/frontwidth storage optimization are described. Finite element modeling considerations and future directions of this research are also presented.
