I have a bridge where I need one span to have a different girder concrete strength than another span. When I update the concrete strength in "Data Modification" and edit my beam strand pattern, all the dead load deflections are zero. I'm currently using version V18U2. When I try re-running the analysis then going back to my strand pattern, it changes it back to the original concrete strength. Any suggestions?
If the program is not retaining the changes then please the follow the steps mentioned in the attached communities link.

If the above solution does not work then please download the latest version V19.01.00.11 from Bentley select server and retest this issue.
