Analytical methods based on truss and arch mechanisms were proposed to predict the ultimate shear strength of prestressed concrete members. Yielding of longtitudinal mild steel bars and prestressing tendons were taken into account. Bond capacity of prestressing tendons was also included in the analyses. Test results from 119 prestressed concrete beams and columns in the past literature were compared with the analytical results in terms of the ultimate shear capacity. The proposed methods gave a better and more accurate estimation of the ultimate shear capacity than the method provided in the standard for design and construction of prestressed concrete structures published by Architectural Institute of Japan. The accuracy did not depend on the experimental parameters such as shear reinforcement ratio, axial force level, shear span ratio and concrete compressive strength specified for the specimens.
