Q: Built-up compression members are connected using
  • A. Lacing only
  • B. Battens only
  • C. Both lacing and battens
  • D. Welding only
Correct Answer: Option C - Built up compression members– Built up section are very commonly used for bridge, trusses and columns for water tanks, towers and antennas. When compression members are required for large structure, it will be necessary to use built-up sections. These built up compression members are composed of two or more structural sections connected by transverse members which can be batten plates, lacing bar, or perforated plates.
