| Abstract: | Based on curve formulae of differential geometry, unified method and simplification for calculating equivalent load caused by tensioning tendons of normal parabolic profile are established. Through calculation and analysis, utilizing range of the traditional method for calculating equivalent load is given, which provides the reference for rational design of special constructions such as transferring prestressed concrete girder, etc. |
