Cable Force Optimization of Norea Extradosed Cable-stayed Bridge
In order to determine the optimal bridge force of Norea three-span cale-stayed bridge in Cambodia,the rigid support con-tinuous beam method,minimum bending energy method and influence matrix method are used based on the finite element model.The results show that the three optimization method to get the matrix method,the final optimization cable value compared with the original design value,analyzed the internal force,displacement and stress change of cable-stayed bridge,under the action of constant load or constant load +additional load combination,the optimized cable force distribution is more uniform,the structure of the overall moment,displacement and stress are reduced,and short tower cable-stayed bridge overall stress and linear shape is more ideal.
