During a construction stage analysis, I used the option "Constriction Stage Analysis Control Data - Load Cases to be distinguished from Dead Load for CS Output" to create a separate load case to examine the effect of the wet concrete and the construction loading to CS2. However, running the analysis with the load cases separate from the Dead Load (CS) produced a considerably different bending diagram than anticipated. Can you explain why there is a discrepancy, given that I assumed they would produce the same bending moment diagram? The details of the construction stages and the results are attached below.
