Steel Structure Design - Engineering

Q1:

In a built up section carrying a tensile force, the flanges of two channels are turned outward

A to simplify the transverse connections

B to minimise lacing

C to have greater lateral rigidity

D all the above

E none of the above.

ANS:C - to have greater lateral rigidity

For Compression, The two channels will be connected as open web column by Lacing.

For Tension, The channels connected back to back itself, So its tensile strength more in lateral direction.
