The dassical ultimate strength-based flexural design of prestressed concrete (PC) beams having Tshaped sections is extended here to a performance-based flexural design by prescribing the strain of tendon at the stage of ultimate bending of the section. The section satisfies design requirements of both the strength and deformation, and is called here the performance-adaptive section. A simple and practical method for obtaining the performance-adaptive section is presented, and the performance of the resulted section is examined by the elasto-plastic analysis of moment-curvature relationship. it is demonstrated that a good agreement between them is obtained. An example of the method applied to the design of a PC slab of double-T type is also presented.
