Abstract:
Aim is the study of the cracking of partially prestressed concrete beams under increasing load up to failure. Different combinations of prestressed and nonprestressed steel were used. The strength of the nonprestressed steel varied between 40 and 250 ksi. Spacings and crack widths were measured and reported. An expression is introduced to calculate the maximum crack width of partially prestressed concrete flexural members.
