In As4100 code, Effective length Le = kl*kt*kr*l.
Does this l equal to UNB or UNT (if specified) whichever is applicable?
In other words, does this l is represented by UNT / UNB parameter in
STAAD.Pro AS4100 as kl, kt and kr are represented by SKL, SKT and
SKL respectively.
Briefly, is UNT / UNB equal to l or Le?
If the same is equal to Le, what will happen if SKL, SKR and SKT are
input with UNB/UNT as well?
