[Possible Bug] Creep and Shrink Analysis is Successful for Solid Section but Unsuccessful for Hollow Section

Solid section [image] [image] Hollow section [image] [image] The construction stages are as follows CS NO TYPE T TITL 10 G_1 0 ‘Steel Angles’ 20 G_1 0 ‘Concrete’ 30 C 10 ‘C + S’ 40 P 0 ‘Post-tensioning’ For solid section, the analysis is successful, but for hollow section, the analysis result …

I made a very simple one span beam to test, and found something weird to me.
