There is no such thing. Each building or structure must be assessed by someone who knows what she/he is doing, namely, an engineer.

Thank you but there are parameters should taken in consideration ( i.e load , moment ....) to estimate number of columns and steel bar there should be a basis for that or not ?

<...I'm not civil engineer...>

That's why not just anyone can design structures. It takes academic study and practical training.

Rather that than base a design on some random comments in an anonymous global Engineering forum, eh?

No can do. This will depending upon such factors as structural load, local environmental conditions etc. Only a qualified structural engineer is allowed to do this.

You should take two weeks off and find a new hobby.

Thank you for your joke ( if it is )

You are trying to learn Structural Engineering in a few lines. You need to know the basic theory of Mechanics, Materials and Structural Engineering in depth to find what you are exactly looking for. However, there are some rules of thumb to find steel weight in a average house. You can estimarte the tonnage of steel at 8 pounds per square foot for estimation purpose only.
