Hi
Im working on a timber frame structure.
When doing member definitions for timber columns I would like to apply a initial deflection. In practice all columns are not perfectly linear, and to the eccentricity will give a moment.
How can I apply this initial deflection of columns?

You can use the geometrical imperfection as shown on the attached picture.

When using the Imperfection definition and "user defined" I have set e0 to 0,0025*L.
When I open this dialog again e0 is 0,00*L
I guess this means that e0 still is 0,0025*L, but all decimals are not showing.
Correct?

Correct. You can check after changing the display format for the corresponding units in Job Preferences.
