Strange Results UZ

355 Views, 6 Replies

Hello,
During my undregraduate disertation in Aristotle University of Thessaloniki, I work on Educational RSA on a column loss case of steel building. Although my model seems to be rational as far as the rest of the results are concerned, the UZ displacement of the node (128) above the lost column  during non linear plastic analysis appears to be paradox. In detail the displacement for dead load case 1 (SW) are bigger than the respective for the G+0,3Q combination. I attach my file and photos of the results. What would  you propose to me?
Thank you in advance

PS: Only one beam has plastic properties (132)

My assumption is that you ignored the lack of convergence warning displayed in v.2011 and checked the results obtained for divergent non linear analysis which couldn't have been be correct. Please use v.2012 instead where the analysis converges.

I'm attaching the values from v.2012.
