- Abstract
To determine the cable forces of long-span cable-stayed bridges in the final state, a new mathematical model of cable force optimization was established with consideration of stress and deformation of bridges. The standard imperialist competitive algorithm was improved based on computational accuracy and convergence speed. A new cable force optimization technique was presented by the proposed modified imperialist competitive algorithm, penalty function technique and finite element method. A real bridge was used to conduct the cable force optimization by the cable force optimization technique. The results show that the proposed methodology has well global searching ability and can well solve the cable force optimization for long-span cable-stayed bridges . The proposed methodology can produce more reasonable stress state with good structural configuration when various nonlinear effects are considered fully in the methodology.
