I am applying loads due to special load as dilatation in robot. I have two issues. the software some not able to account for P-delta second order effects. The self-wight cause bending and deflection that shall increase due to compression force from the actions applied as dilatation.
Also, the steel design, i cannot seem to be able to get the software to calculate the buckling parameter although I have defined this I think properly.
see attached images.

Thanks. The deflection seems to work now but the software still not show the extra bending moment due to P-delta for the deformed shape
In my opinion there is no p-delta effect in this model since there is no displacement in direction Z global at the end of bars (supports). The addition bending moment (Dilatation force X dZ) doesn't exist.
Anyway, I don't know if you really activated P-delta, so see this image below.
Best regards,

Another thought:
I think you wanna count with "small p-delta" instead of p-delta.
Maybe this thread can help:
" In the current version of Robot only P-∆ is implemented. The P-δ can be accounted for by defining some nodes along the bars"
