How many bars are used in column?

Formula we used for calculate number of steel bars in column,1) Ag = Ac +Asc, this formula is used to find out gross area of concrete, if size of column is given. 2)Asc=Ag-Ac, this formula is used to find out area of Steel used in RCC column, if their gross area and concrete area is given.

Which bar is used in column?

Size of Steel bars used in building construction are 6mm, 8mm, 10mm, 12mm, 16mm, 20mm and 25mm. 6mm & 8mm size/diameter of steel bars are used for stirrup formation, 8mm to 12mm size/diameter of steel bars/tmt bars are used in slab and 12mm to 25mm size/diameter of steel bars/tmt bars are used for beam and column.

What is the full form of TMT bars?

The full form of TMT Bar/Rebar is Thermo Mechanically Treated bars. We all know that TMT Bars are essential for all type of construction purposes but it is also important to know how it is made. Best Quality TMT Bars pass through series of processes that determines the strength & flexibility of it.
