Column cracking results in different ROBOT versions

[cernevicius.karolis]

I calculated the same model in two different versions of ROBOT and for some reason when calculating cracking in RC column, RSAP 2017 shows internal forces equal to 0 and it doesn't include the load combination used, while RSAP 2023 shows reasonable values and the load combination. Is there a way to fix it in 2017 version?

HI @cernevicius.karolis 

Could you share model from Robot 2017 for verification. Zip it before sharing

Good evening, @Krzysztof_Wasik 
Attaching the model over here. For the record, required reinforcement module for columns shows different results as well and cracking in 2017 is showed as 0 and in 2023 is a reasonable value. Beams and slabs seem to match, but not the columns. I asume, that for some reason, 2017 version is ignoring a cracking check.

HI @cernevicius.karolis 

Which column number is verified in post 1

[cernevicius.karolis]

@Krzysztof_Wasik I don't remember specifically, which one was it, but it works on any of the columns. Column No. 328 is a good example of that. Here's an example:

Hi @cernevicius.karolis 

I have calculated provided reinforcement with cracking check for column 328

Cracking is calculated.

I see that model is created in out of box Robot 2017 (30.0.0). Try to update your version. I am using 30.0.2

Link to hot fix 2 available in this article

@Krzysztof_Wasikwhenever I try to install the hotfix I get an error. Is there a way to fix it? The program is obviously installed on the computer, but hotfix cannot find it for some reason.
