Hi,
 
I have some old W6.8.5 [6B8.5] beams to check for combined axial and bending element.
 
I got the property of it as follows:
 
wt. =    8.5 lb
area =   2.5 in"2
depth =  5.83
flange = 3.94x0.194 inch
web thickness = 0.170
d/Af =  7.63
Ixx =    14.8 in^4
Sxx =     5.07 in^3
rxx  =   2.43 in

Iyy = 1.89 in^4
ryy = 0.87 in
 
How can I find out the "Cw-warping constant" for this shape?
 
Thanks
 
Sam
