A 1.75-m-wide square footing is placed at 0.5 m depth in the ground where c′ = 10 kN/m2 , ϕ′ = 33°, and γ = 19.0 kN/m3 . The column load consists of 60% dead load and 40% live load. Determine the maximum allowable column load by LRFD, assuming the following: Ψ = 1.25 for dead load Ψ = 1.50 for live load Φ = 0.45 for the ultimate bearing capacity Use the following bearing capacity equation with Meyerhof’s N
