Hi all,
I am trying to apply an offset for a simple connection of a beam to column (See Fig 1 and 2 below). This is in order to simulate the eccentric loading at the connection between beam and column (large UB sections are being used for the columns).
After applying the offset and analysing the structure, the deflections of the beams and columns at the location of the offset have increased hugely, (the offset has lead to a mechanism being formed? ) see Fig 3 below.
Does anyone know the possible reasoning behind this ?

My understanding is that without these offsets the results are as expected - is this correct? If yes, have you ignored any displayed warnings? If not, could you attach the model?
Yes Artur, the results are as expected without the offset applied (see Fig 1 below).
No warnings are displayed during the analysis of the structure.
First of all mind to display exact deformations rather than deformations when you have such definitions of offsets. In addition I would remove the releases for inclined columns so to avoid the situation that all bars which meet in the common node have bending releases defined (and then of course I would check the value of bending moments for the bars deleted the releases from 🙂 ).
