Question
Example: Compute the available strength of the compression member shown in the figure. Two angles, 5 x 3
x 1/2, are oriented with the long legs back-to-back (2L5 × 3 ×12 LLBB) and separated by 38 inch. The
effective length KL is 16 feet, and there are three fully tightened intermediate connectors. A36 steel is used.
For each component
For 5 x 3 ×1/2 A=3.75 in?
