Grit impregnated epoxy coated strands may be modeled. The recommendatons presented in "Guidelines for the use of Epoxy-Coated Strand", PCI Journal, July-August 1993 are used for transfer length and relaxation losses.

Transfer Length

The recommended transfer length is 50d_b.

Relaxation

Relaxation of epoxy coated strands is taken to be double that of uncoated strands.
