Stiffness matrix
Posted: 01 May 2020, 23:00
Hello!
By EN-8 for stiffness matrix we mast to use one-half of the corresponding stiffness of the uncracked elements.
In the Help System i found:
Sections ->
"The EA, EI & GJ values shown in this module are merely indicative (i.e not used in the analysis) and calculated using the elastic material properties of the main section material (i.e. concrete in R/C sections and steel in steel sections)."
What EA, EI & GJ values the program use?
Thank you!
