Q: Compression members composed of two channels back-to-back and separated by a small distance are connected by riveting so that the minimum slenderness ratio of each member between the connections, does not exceed:
  • A. 40
  • B. 50
  • C. 60
  • D. 70
Correct Answer: Option A - A compression member composed of two angles channels or tees, back in contact or separated by a small distance should be connected together of riveting, bolting, or welding so that the slenderness ratio each member between the connections is not greater than 40 or 0.6 times the most unfavorable slenderness ratio of the strut as a whole.
