Question: A W 1 4 1 7 6 , A 9 9 2 member is proposed for use as a 1 2 . 5 f t
A W member is proposed for use
as a column in a moment frame. The frame is
designed so that under a service lateral load
kips, the frame drifts no more than The total
story load, is times the individual column
load. Analysis results are from a firstorder analysis.
Will this member be adequate to carry a no
translation compressive dead load of kips and
live load of kips? The top of the column is
loaded with a notranslation dead load moment of
kips and a notranslation live load moment of
kips. The translation moments applied to that column
end are a dead load moment of kips and a live
load moment of 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 Determine by a LRFD and b ASD.
