RAM Concrete Column - Eurocode UK NA Slender Column Design

Can you send your file? I am getting results in a test file for a slender column, EN codes, version 16.01.00.20.  There may be a point at which the column becomes too slender to give capacity results. Secure File Upload

Done. I must say I am not particularly interested in the upper floors, as they will be done by others. I am also unsure as to the column boundary conditions in the lowest level. I want to use the Foundation Loads feature of RAM Modeller to get my reactions, but since the columns effectively only run through the slab, I don not know how to get accurate results.

In your new model, in v17, I get a warning in Ram Frame about the mesh quality but it does not stop the program. Where are you seeing a problem specifically? 

In v16.01.00.30, it gives me error messages for the slabs on the left hand side on the first and second story. However, it does this while it is creating the framing tables. I am not sure if the model I upload was framed. Perhaps forcing a reframe would lead to the same error.

OK, I can get that error too, but it still runs, and the total reactions (e.g. from the Ram Concrete analysis) look reasonable. Load diagrams on the beams look fine too. 

Ah, okay, I though it was not applying anything. Does this mean that RAM Steel & RAM Frame Steel will run properly despite this?

I checked the total dead load reaction from the Concrete analysis (Vertical reactions report) compared to the diaphragm force totals and it's within 0.3%, so I think it's OK.
