Peak load

Post by PH 1255 » Wed Aug 03, 2022 2:29 am

Dear STKO team:
I am building a model about an axially compressed column considering different slenderness ratios of steel bars (here, slenderness ratio = 20), as shown, the dashed line represents the experimental curve and the solid line represents the simulated curve. I have some problems now, from the graph, the trends of them are similar, but in the peak load and onward curves, the simulated values are much higher than the experimental values, I've tried to decrease E, fcp, ep, Gc in DamageTC3D, but there are no effects. Is there any way to solve this problem please? thank you.

I tried your model with another GaussRandMaterialTable and it seems to work really well.
Are you sure the values you have in your GaussRandMatTableMaker.py are the same as those in the DamageTC3D?
I'm pretty sure in the python file you have higher values from another analysis
