Reference ESR-4868 Table 15 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) =( 19,258 lb / anchor) / 1.0
N ba = 19,258 lb / anchor α N, seis = 1.0
= 19,258 lb / anchor 0.55 ϕ bond N ba, sustained ≥ N ua, s ϕ bond = 0.65
0.55( 0.65)( 19,258 lb / anchor) = 6885 lb / anchor 6885 lb / anchor > 750 lb / anchor OK
N ua, s = 750 lb / anchor Reference page 132.
