Hello,

Is there a reference (publication) for the section state determination used for the NDFiberSection3d section? Especially for the matrix relating the section deformations to the fiber strains (axial and shear distribution)

Thanks,

Hello,

If I define a zero-length rotational spring along the x-direction for a 3D model without specifying the local axis, does this imply that the positive moment and rotation will be in the positive global x-direction, and this is independent of the order of spring end nodes I and J?

Thanks a lot

Hello, What does the chord rotation recorder do in a force-based beam column element? I am modeling a cantilever column with axial and lateral loads, and I obtain a non zero chord rotation at the free end. I am not sure why this happens since the inflection point is at the free end. Thanks a lots fo...

Hello, I am trying to simulate a column loaded axially with a constant axial force, and with 2 lateral loads (in the X and Z directions) and with an imposed top rotation along the Z-direction. The load controlled axial load is fine, however, I have some problems when trying to add the 3 different di...
