Abstract
A flexural analysis method of precast prestressed concrete beams considering bond-slip characteristics of prestressing steels and deformations of flexural shear cracking was proposed. In this analysis method, the widths of flexural shear cracks are evaluated as the pullout of stirrup, based on the bond force distributions of prestressing steels and tension reinforcements due to the bond-slip analysis. It is concluded that the load-deflection relationships, the crack patterns and the strain distributions of prestressing steels and stirrups in test beams can be simulated by using this analysis method.
