9.11. Design the reinforcement for a 16 in. x 22 in. braced rectangular reinforced concrete column that can support a factored axial load P = 500.000 lb and a factored moment M₁ = 3,500,000 in.-lb. The unsupported length, , of the column is 10 ft. Assume that the end moments M, and M₂ are equal. Given: f = 4000 psi, sand-lightweight concrete f₁ = 60,000 psi d' = 2.5 in.
