Question: A W 1 4 * 1 7 6 , A 9 9 2 member is proposed for use as a 1 2 . 5 ft

A W14*176, A992 member is proposed for use as a 12.5 ft column in a moment frame. The frame is designed so that under a service lateral load H =120 kips, the frame drifts no more than L/500. The total story load, Pstory, is 15 times the individual column load. Analysis results are from a first-order analysis. Will this member be adequate to carry a notranslation compressive dead load of 160 kips and live load of 490 kips? The top of the column is loaded with a no-translation dead load moment of 15 ft-kips and a no-translation live load moment of 30 ftkips. The translation moments applied to that column end are a dead load moment of 80 ft-kips and a live load moment of 250 ft-kips. The column is bending about the strong axis. The lower end of the column is considered pinned and the effective length factor is taken as 1.5. Determine by (a) LRFD
