RFCR x RFID x RFD
RFCR = Reduction factor for creep
RFID = Reduction factor for installation damage
RFD = Reduction factor for durability
NOTE: this equation does not include other reduction factors
that may apply to design. Reduction factors are site specific
and should be reviewed on a per project basis. Contact the
manufacturer for recommendations.
