Abstract
This paper presents the development of analytical equations for transfer length, flexural bond length, and development length of pretensioned strand in prestressed concrete, and compares them to experimental results in the literature. The transfer length equation assumes a plastic zone and an elastic zone within the transfer length. Similarly, the flexural bond length equation assumes plastic and elastic zones, and the development length is the sum of the transfer length and flexural bond length. The analysis considers both uncoated and epoxy coated strand. A numerical example is included to show a typical calculation for the development length of epoxy coated prestressing strand.
