Moment of inertia for a W8x17

(OP)
I evaluating a couple existing beams (late 70's building) and don't have the moment of inertia for a W8x17.  Does someone have it?  Thank!

From the 6th Edition of the AISC (publish date 1966) WF 8x5-1/4, 17 PLF: , A=5.0 in2,web t=0.23 in, d/Af=4.95,Ix=56.4 in4, Sx=14.1 in3, Iy=6.72 in4, Sy=2.6 in3

The values in the 7th edition manual are slightly different.

W8x17
A=5.01 in2
d=8.00 in
bf=5.250 in
tf=0.308 in
tw=0.230 in
Ix=56.6 in4
Sx=14.1 in3
rx=3.36 in
Iy=7.44 in4
Sy=2.83 in3
ry=1.22 in
rT=1.40 in
J=0.147 in4

RE: Moment of inertia for a W8x17

I think the 8th ed. of AISC was the last to publish the W8x17 specs.

RE: Moment of inertia for a W8x17

It's not in the 8th edition.  It looks like the W8x17 was modified slightly and became the W8x18.
