Name: __________________________________________________ PID: ________________

The various axial loads for a building column have been computed according to the applicable

building code, with the following results: dead load = 200 + A = _____ k; load from roof = 50 +

B _____ k (roof live load); live load from floors (reduced as applicable for large floor area and

multistory columns) = 250 + C = ______ k; compression wind = 128 – D = _____ k; tensile wind

= 104 – E = ______ k; compression earthquake = 60 – F = _____ k; and tensile earthquake = 70 –

G = _____ k.

Determine the critical design column load, Pu, using the LRFD load combinations.

(If your PID is “5684659”, then A = 5, B = 6, C = 8, D = 4, E = 6, F = 5 and G = 9)
