Q: Lug angles .............
  • A. Are used to reduce the length of connection
  • B. Are unequal angles
  • C. Increases shear lags
  • D. All options are correct
Correct Answer: Option A - Lug angle– It is short length of an angle between section used as a joint to connect the outstanding leg of a member, by reducing the length of the joint. • lag angles reduces shear lags • The channels get twisted symmetrically with regard to its axis parallel to web. • Twisting takes place about the axis which has less moment or inertia or least radius of gyration.
