A moment frame is designed so that under a service lateral load

, the frame drifts no more than

. There are a total of 15 columns in this frame, so

is 15 times the load on this column. A

, A992 column is to be checked. Analysis results are from a first-order analysis. The column is called upon to carry a compressive dead load of 100 kips and live load of 300 kips. This load will be taken as coming from a no-translation analysis. The top of the column is loaded with no-translation dead load moment of 25

and a no-translation live load moment of

kips. The translation moments applied to that column end are a dead load moment of 35 ft -kips and a live load moment of 100 ft -kips. The lower end of the column feels half of these moments. The column is bending in reverse curvature about the strong axis. Will the W14

, A992 member be adequate to carry this loading? Analysis shows that the effective length factor in the plane of bending is 1.66. Determine by (a) LRFD and (b) ASD.
