Q: Rolled steel joist means
  • A. Rolled steel I section
  • B. Rolled steel angle section
  • C. Rolled steel channel section
  • D. Rolled steel T section
Correct Answer: Option A - Rolled steel joints defined as rolled steel I section. In the I section more than 85% of shear force is registered by web. Hence the web resist the shear force and flange resist most of the bending moment in rolled steel beam. • Rolled steel joists are some time called I section or RSJ.
