d) Radius of gyration about x- axis
e) Radius of gyration about y- axis
f) Slenderness ratio of column in x-axis
g) Slenderness ratio of column in y-axis
h) Maxmimum slenderness ratio
i) Allowable compressive stress
j) Allowable axial compressive load

2. Select A36 columns of the frame shown. Assume to be braced in plane perpendicular to frame. Girders are W12x106
3. Truss shown is constructed of a variety of members, all of which are assumed to be pin ended. Determine whether all members are adequate, specify replacements with same nominal depth. Assume top chord is braced laterally at every joint.
Top and Bottom Chords W8x24 (A36)
Diagonal bracing L3.5 x 3.5 x 3/8 (pair)
Vertical members L 4 x 4 x 3/8 (pair)
4. A tall column is as shown. The strut is the lateral bracing. No compression flange support. Select an economical A36 W18 section based on stress and deflection.
