Can Rebar area size of columns vary for different floors?
Can Rebar area size of columns vary for different floors?
(OP)
Hello,
I have designed 2 storey building but rebar size varies for columns at 4 corners.. bottom storey rebar area size is 700 mm2 and top storey rebar area size is around 1464 mm2. So am I doing anything wrong or results are acceptable?

You have to design them... but this could be unsafe if you require greater vertical reinforcing for the columns above. Safer to use the reinforcing required for the columns above, but, you have to design for the loading... axial load and moment.

But to his/her credit the original poster is at least questioning the results.
I suspect that the problem lies in how we are educating today's engineers. I suspect that they are being taught how to model and not how to design. They are learning how to manipulate software and they are not learning how structural framing systems work. I don't think anyone should be using structural engineering software who does not know how to manually design the structures that they are modeling. Structural engineering software should be used as a tool to improve productivity, not as a crutch to bypass the need to have a thorough understanding of the codes and design standards and the need to have a fundamental understanding of how structures work.
I apologize for sounding like an old curmudgeon (which I suppose I am).
