Procedure

Level 1:

• Input the Working Load (P) in kN
• Specify the design value for concrete strength (f_ck) in N/mm²
• Specify the design value for steel yield strength (f_y) in N/mm²
• Enter the column width (b) in mm
• Provide the column depth (h) in mm
• Input the Safe Bearing Capacity (SBC) of the soil in kN/m²
• Enter the effective cover (d') in mm
• Once all the basic design parameters are entered, click on "Configure" to proceed to the next level.

Level 2:

• Calculate the following:
  • Factored Load (P_u) in kN
  • Self weight
  • Total Load (kN)
  • Area of Footing (A_f) in m²
  • Length of footing (L_f) in m
  • Width of footing (B_f) in m
  • Soil Pressure (W_u) in kN/m²
• After three incorrect attempts, the correct formula and answer will be displayed.
• After calculation, proceed to the next level.

Level 3:

• Calculate:
  • M_ux, _Muy
  • d_x, _dy
  • Total depth
• After three incorrect attempts, the correct formula and answer will be displayed.
• After calculation, proceed to the next level.

Level 4:

• Calculate Ast_x
• Select the bar diameter to be used
• Calculate the area of one bar
• Spacing will be calculated
• Then calculate and enter the value of:
  • Area of steel provided
  • pt% (percentage of steel)
• After calculation, proceed to the next level.

Level 5:

• Similarly, calculate:
  • Ast_y
  • Other different parameters with conditions
  • pt%
• After all calculations, click on "Submit"
