Question

10.3.B) Determine the maximum factored axial compression
load

for a W 12 × 120 column with an unbraced height of 22 ft if both
ends are

fixed against rotation and horizontal movement.

**use A996 steel with Fy = 50 ksi.**

Answer #1

Determine the maximum factored axial compression load for a W 12
X 45 column with an un-Braced height of 14 ft. consider the
following:
K = 1
Fy = 50
530
322
335
559

Determine the maximum factored axial compression load for a W12
x 72 column with and unbraced height (both axis) of 18 foot.
Rotation and translation is fixed at the bottom and top of the
column.
Group of answer choices
813 kips
729 kips
547 kips
678 kips

Select a light W shape for a column subjected to an axial
compressive load of 1623kN. The unbraced length of column is 5m and
the ends are pinned. Use A36 grade steel.

determine the adequacy of a 12-ft long W12x40 column in a braced
frame to resist a factored axial load of 120 kips and factored
moments of 125ft-kips and 55ft-kops about the x and y axis,
redpectively. The column is assumed to be painted at both ends. Use
ASTM A992 steel.
