Sustained Tension Load Check ACI 318-19 Eq.( 17.5.2.2)
0.55 ϕ bond N ba, sustained ≥ N ua, s
Reference ESR-3814 Table 11 for ϕ bond-value. N ba = λ a α N, seis τ xxxx π d a h ef Reference bond strength calculations above for N ba-parameters. N ba, sustained = N ba /( α N, seis)
=( 44,664 lb / anchor) / 1.0 N ba = 44,664 lb / anchor α N, seis = 1.0
= 44,664 lb / anchor 0.55 ϕ bond N ba, sustained ≥ N ua, s ϕ bond = 0.65
0.55( 0.65)( 44,664 lb / anchor) = 15,967 lb / anchor 15,967 lb / anchor > 375 lb / anchor OK
N ua, s = 375 lb / anchor Reference page 74.
