Abstract:

Article Preview

By the force analysis of continuous rigid frame bridge girder, the depth-span ratio’s influence on the structure in load carrying was studied, the relationship between the depth-span ratio and prestressing force required by structure was established, and using the sectional force of girder in the construction and utilization of the bridge as the constraint, with the application of grid search method and the construction case of Ziyang bridge, we carried out the optimization of design on the depth-span ratio for continuous rigid frame bridge girder.
