Hello Hugo,
there are many possible reasons for the difference, however, the fixed/rotated cracks setting only has influence on growth of already existing cracks, not initiation of new ones.

I would suggest to send your model (without results, ZIPped) and the reinforcement load-displacement graph to our support mail (cervenka at ...). Including a sketch or photo of the test setup is not a bad idea if available.

Hello!

I'm a PhD student of the Civil Engineering Department and i'm trying to modulate some RC beams externally reinforced with GFRP. At this point, i allready tested one beam unreinforced. The results are pretty good however, the experimental results (p.e. Force vs displacement graph) shows concrete cracking at 9kN and the ATENA shows almost twice this value. I'm using fixed crack and i remember an article of prof. Cervenka saying that fixed crack gives minor displacement... i'm supposing that the cause may be here... it is possible? or it is something else? if it is something else, what is it?

Thank you for your attention,
Best wishes,
