A fundamental aim of prestressed concrete is to limit tensile stresses, and hence flexural cracking, in the concrete under working conditions. Design is therefore based initially on the requirements of the serviceability limit state. Subsequently considered are ultimate limit state criteria for bending and shear. In addition to the concrete stresses under working loads, deflections must be checked, and attention must also be paid to the construction stage when the prestress force is first applied to the immature concrete. Design of prestressed concrete may therefore be summarize as design for serviceability cracking, check stresses at transfer, check deflection, check ultimate limit state-bending and design shear reinforcement for ultimate limit state.
