PROCEDURE

Configuration:

• Configure the parameters such as working load (KN), grade of concrete, grade of steel, unsupported length l_x (m), unsupported length l_y (m) and support conditions.
• Proceed to the next step by clicking on the next arrow.
• Calculate factored load (P_u), effective lengths lx_eff and ly_eff in mm. After three incorrect attempts, correct formula and value will be displayed.
• Proceed to the next step by clicking on the next arrow.

Calculations:

• Assume and enter the value of A_sc within the range of 0.8% to 6% as per IS 456:2000, Clause 26.5.3.1 a. Values of A_g, A_c and A_sc will be displayed.
• Select the type of column. Proceed to the next step by clicking on the next arrow.
• Enter the value of b/D ratio. After clicking on submit button, checks for short column and axially loaded column along with dimensions of column are displayed.
• Proceed to the next step by clicking on the next arrow.
• Enter the diameter of longitudinal bar which should be more than or equal to 12 mm as per IS 456:2000, Clause 26.5.3.1 d.
• Enter the number of bars. Enter the diameter of lateral ties to be provided. Enter the value of cover to be provided in mm.
