Re: How to support a structure in only one direction

Very true and obvious :smileyhappy: duuh!

 

A combination between a case (that stand alone gives incorrect results) with other cases provides correct results, that whas my concern; but you cleared it.

 

( I could be a little bit nosey and ask who/why does this happen, but I shouldn't go offtopic, so i'll ask this later)

 

THANKS AGAIN for your anwsers, very helpfull.

If you mean why lateral load case does not converge then check it may happen that just overturns the model (all UZ+ supports are switched off as the model starts to rotate). In other words check where your neutral axis is located vs. the support arrangement.

I fixed the convergence problem using a combination between these two suggestions: http://forums.autodesk.com/t5/Autodesk-Robot-Structural/Nonlinear-analysis-Iteration/m-p/3385747/hig... http://forums.autodesk.com/t5/Autodesk-Robot-Structural/convergence/m-p/3469484/highlight/true#M5032 Now everything looks fine, the reactions are all positive or 0 for the UZ+ supports. Thanks, again for your support.
