| Abstract: | A double-curvature arch bridge is one of the most bridge-types in the transformation.The application of an augmented section method in reinforcing the double-curvature arch bridge is presented here,and the structural stress conditions before and after reinforcement are studied with a large scale finite element software named as MIDAS Civil.It is concluded that the load-carrying capacity of the double-curvature arch bridge can be improved through the reasonable augmented section method. |
