Partially prestressed concrete beams, those which are designed for a limited level of tensile stress, have several advantages over their fully prestressed counterparts — there is a better control of camber, a savings in prestressing steel and end anchorages, and a more economical utilization of mild steel. Partially prestressed concrete beams do, however, have several disadvantages: 1) Reduction in the ultimate strength; 2) increased deflection under overload conditions; and 3) cracking. This note is based on a recent study of flexural cracking in partially prestressed concrete beams which include the examination of all available experimental data.
