diferent section properties for forces and verification

[aruser]

possiblity to use some section properties for the forces and displacement calculations, and other ones section properties for the member verification.

For example, use the gross properties for the obtaining of the inner forces and displacemente while after using the effective properties for the code verification

Effective properties refering also to input for instance test values, etc.
