Self weight and cross section problem

Hi all,

I have a small problem that I can't understand what's happened here.

Could anyone help me this?Cont%20beam%20calculate.gh

As you see in the picture. If I enable the cross section component, the moment will be change ( even though i didn't take self weight into account) so the value might not correct. I checked by another program and it gave me the result like this: (it's the same when I disable the cross section component.)

Thank you,

Dear lamvd,

the discrepancy comes from the fact that Karamba includes shear deformations. Disabling these in Karamba gives the same results as those in the reference calculation (see attached definition).

Best,

Clemens
