| Abstract: | The slant legged rigid frame bridge with multi-span and non-abutment is a higher degree redundant structure, such as temperature change, shrinkage and pier deformation which become the important factors for controlling the stucture design. In order to solve this problem and according to the engineering practice, the locating hinge method of the rigid frame bridge with multi-span non-abutment slant legged is brought, the internal force of the slanting legged rigid frame bridge with multi-span and non-abutment before and after locating hinge analyzed and then the reasonable locating hinge position found out. |

| Keywords: | slant legged rigid frame bridge without abutment shear hinge locating hinge position |
