| Abstract | Theoretical expressions for predicting the maximum crack spacing and crack width in the constant moment region of a bonded prestressed concrete beam are derived. A parametric study is made in order to predict the influence of the variation in the prestress level, bond stress, steel percentage, eccentricity of reinforcement, steel diameter, and the concrete strength on the width and spacing of cracks in a bonded prestressed concrete beam. The results of the analysis indicate that increasing the amount of prestressing force, bond stress between the concrete and the reinforcement, steel percentage, eccentricity of reinforcement, and decreasing the steel diameter, decrease the width and spacing of cracks. The variation in concrete strength has no apparent effect on both crack width and crack spacing. The cracking moment of the beam is significantly affected by the prestressing force and concrete strength. An increase in the level of prestress and concrete strength increase the cracking moment of the beam. |
