aluminum design manual
does anyone have an aluminum design manual?  i have an american std. structureal aluminum channel c4x2.16.  i am looking for the area, radius of gyration about weak axis, moment of inertia and possibly an allowable axial column load at 3ft of length.
this information would be greatly appreciated.
thank you,

from the aluminum design manual:
c4x2.16
a = 1.84 sq. in.
ry = 0.45 in.
ix = 4.19 in^4
iy = 0.37 in^4
column capacity depends on the value of k, and the type of aluminum.  
you're definitely into column buckling for slenderness.  also, you may have significant bending stresses about the minor axis, unless the load is concentric...
you also need to check the flange buckling and possible load eccentricity (real life - not theory)
