Table 10.1—Sustained plus cyclic service load stress limits in FRP reinforcement should be limited as expressed by Eq. (10-8) to maintain safety. Values for safe sustained plus cyclic stress levels are given in Table 10.1. These values are based approximately on the stress limits previously stated in Section 4.4.1 with an imposed safety factor of 1/0.6 ff,s ≤ sustained plus cyclic stress limit (10-8)
