Question
The column shown below is subjected to the factored axial force and bending moments about
its weak and strong axis. Use the LRFD method to control whether W14x132 is strong enough to
carry the combination of axial force and bending moments by:
Md = 50 kip-ft
MI = 40 kip-ft
Md = 100 kip-ft
MI = 80 kip-ft
Pd = 400 kip
Pl = 300 kip
Pd=400 kip
Pl = 300 kip
Md = 50 kip-ft
MI = 40 kip-ft
Md=25 kip-ft
MI = 20 kip-ft
Md=25 kip-ft
MI = 20 kip-ft
L= 15 ft
Md = 100 kip-ft
MI = 80 kip-ft
Pd = 400 kip
Pl = 300 kip
x
Md=25 kip-ft
MI = 20 kip-ft
I
Md=25 kip-ft
MI = 20 kip-ft
Pd = 400 kip
Pl = 300 kip
Note: The second order effects are included in the forces given
a) Determine the Design Compressive Strength of the column
b) Find the value of Cb ad determine the design bending strength of the column about its
strong axis
c) Find the design bending strength of the column about its weak axis
d) Use the AISC interaction equations (H1-1a and H1-1b) to determine the adequacy of the
column
