Column design output

[Ronny_Raygun]

Another question from a new Robot user.

I’ve run the column design calculations on a couple of occasions now and the output does not seem right at all.

The model which you will find on the attached link, (no errors or warnings, and the slab seems OK) has, for example a corner column carrying eight floors apparently only requires 100mm2 reinforcement along “b” and 60mm2 along “h”. It’s providing 2 H20s along “b” and the same along “h”. This is a column that is 200x800mm so it can’t be right.

I have left the preferences as defaults, but to be perfectly honest, my knowledge of EC2 is quite limited and so I'm not sure what I could/should altter.

You can find the model at the following link. Can someone give some guidance on how to get a believable column design, as I do not believe the output that I am getting at the moment.

The actual distribution of reinforcement is as shown on the attached picture.

I don't know what area of reinforcement the user expects but before focusing on this I would check the values of forces used for the design of the column. Are they as expected? If not, check the applied loads and their distribution in the model. If they are as expected what results according to the user should be and why?
