Hi there, I think you should use the beam 0,40m x 0.30m if you model has the beam as 0.40m height (depth), otherwise you will have a beam with 0.55m height. You should not add the depth of the slab to the beam. Only if you need a beam with 0.55m height (depth) you can use this value for the...

You can check the model Analyze>Check.... It is possible to have some errors when the model was defining. Can be from units of some material or section? Is not easy to tell about see how the model was made.

Do you still have this problem? Make an print screen (with print screen button from the keyboard and paste in Paint - software) upload the file and we can judge after that. P.S.: Also it is useful to tell the system configuration and special the resolution you used.
