Optimum design analysis of hybrid cable-stayed suspension bridges
A design methodology to predict cable configuration under DL and LL is proposed. The model evaluates the cable system involving the lowest steel quantity. A FE approach coupled with OMs is utilized to derive the design configuration. A two-step nonlinear algorithm based is developed, avoiding convergence problems. The formulation is validated with existing data available from the literature.
