The maximum out-of-plane deflection (Δ_s) due to service lateral and eccentric vertical loads, including PΔ effects, shall not exceed l_c/150. Where Δ_s is calculated as follows:

ACI 318-14 (11.8.1.1(e))

ACI 318-14 (Table 11.8.4.1)

Where M_a is the maximum moment at mid-height of wall due to service lateral and eccentric vertical loads including PΔ effects.

ACI 318-14 (24.2.3.5(b))

ACI 318-14 (11.8.4.3(a))

Δ_s will be calculated by trial and error method since Δ_s is a function of M_a and M_a is a function of Δ_s.

ACI 318-14 (Table 11.8.4.1)

No further iterations are required

The wall is adequate with 16 #6 vertical reinforcement and 6.25 in. thickness.
