| Abstract | ||
| The optimum geometry design of cable stayed bridges could help in the material and the cost minimization of such structures. An optimum design algorithm has been proposed for the analysis and design of Cable Stayed Bridges (CSB), for their minimum weight. In this procedure, a computational method is presented to determine the initial shape of cable stayed bridges under the action of dead load of the girders and pretension in stay cables. The proposed optimum geometry design is achieved to satisfy both stress and displacement constraints, considering the member sizes and the geometrical design variables. A hybrid method is proposed by using the combination of a derived optimality criterion method and the suggested fully utilized design algorithm. Numerical investigations are performed to verify both the efficiency and the mathematical robustness of the proposed algorithm. The practical applicability of the proposed algorithm is made on the Suez Canal cable stayed bridge; the obtained results are analyzed and discussed | ||
