| Abstract: | A computing method is presented for studying the bending moment, axial force and curvity relationship at the section of prestressed concrete beam. The author computates the relation between bending moment and curvity at the section under different prestressing degrees; and points out the effect of prestressing degree on bending ductility; and puts forward a method for the promotion of bending ductility. |
