Q: In the case of bolted, riveted or welded trusses and braced frames, the effective length, KL, of the compression members shall be taken as ........
  • A. 0.7 to 1.0
  • B. 0.8 to 1.5
  • C. 0.7 to 1.2
  • D. None of these
Correct Answer: Option A - Compression member in trusses: • in the case of bolted, riveted or welded trusses and braced frames, the effective length KL, shall be taken as 0.7 to 1.0 times actual length, depending upon the degree of end restraints provided. • for buckling in the plane perpendicular to the plane of truss, the effective length may be taken as actual length.
