3 years ago @barischrooneyj which part of the implementation would you like to verify?
- creep/shrinkage strain calculation over time (structure independent)?
- creep/shrinkage effect calculation on a structure, e.g. deflections, stresses, internal forces?
If 2. is verified then 1. as well, but 2. is a lot more effort than only 1.
On 1.:
- It is pretty much verified if you compared it to the results of the Mathcad implementation that I shared with you to serve as the basis for the python code. I verified the Mathcad code in the past.
- For a few selected cases you could also use this: https://eurocodeapplied.com/design/en1992/creep-shrinkage.
On 2.:
- It could be compared to other FEA software, e.g. Diana or Midas Civil (in case of the latter I'm sure that it has all the required features and more.) Both are commercial software.
- it could be also verified against analytical calculations for simple cases, e.g. for simple slabs (two-way and one-way as well) we have analytical solutions. This would be weaker than verifying on the bridge 705 model but it would still substantially increase my confidence.
To verify the time series of creep and shrinkage implementations it would be ideal to compare to a second implementation.
