This calculator is useful to determine the strength of axially loaded tied rectangular concrete column with four rebar. It also determines the spacing of ties for the column. This calculator uses FPS/US Customary Units.

Least column dimension should be 8 inch. This calculator determines the area of column, rebar ratio and the axial load capacity of the column as well as the spacing of tie bar spacing of #3 tie and #4 tie.
The user of this calculator is advised to comply with
ACI guidelines
for short column, rebar spacing and cover etc. According to ACI 318-19 the rebar ratio should not be less than 0.01 A_{g} and not greater than 0.08 A_{g}, where A_{g} is the gross area of column.

Please enter the values in the appropriate units mentioned in the form given below and start calculations.
