I am not sure that the elements whose flange checks are required to be performed, must be declared as rigids or not as we used to do the checks manually.

I have a model, in which they are not declared as rigids, and some of the loadings exceed the allowable limits but the results are different when they are declared as rigids.
If they are not to be declared as rigids then there is no way we can enter the weights of the flanges.
Request thoughts...

After entering the rigid weights, Caesar doest not produce the results for flanges.
The software version we have is 5.30.01 (Build 110228). I know it is obsolete but can I expect that the latest version will be able to print the report.

BR,

Maybe you have to activate "Print Forces on Rigids and Expansion Joints"
in the "Special Execution Parameters" dialog.
