A manual calculation procedure is presented for predic-tion of deflection of partially prestressed beams. Adequate accur-acy is achieved by accounting for the important parameters affecting the deflection: creep and shrinkage of concrete, relaxation of pre-stressed steel, cross section areas and locations of prestressed and nonprestressed steel and cracking at the sections where the tensile strength of concrete is exceeded. Design aids are presented to sim-plify calculation of properties of cracked sections. Numerical exam-ples are included.
