• Is UNB/UNT/UNL linked to effective length factors Ky and Kz in STAADPRO?

    Hi all, I was wondering if anyone could provide some clarity on the use of UNL (UNB/UNT) in the case of cantilever members. What I know so far is that Ky and Kz would have some typical factor of 2 or 2.1 for cantilever members, and this impacts the…
  • Question on Modulus of Elasticity of concrete in STAAD

    Hello. How does STAAD compute the modulus of elasticity of concrete (default material properties)? The default values are: fcu is 27.58 MPa E is 21728 MPa Say I would like to use f'c = 27 MPa, what would be the corresponding E and fcu? I know…
