38. Calculation of minimum eccentricity:   As per code IS456:2000   Therefore, additional moment can be neglected . Calculation of area of steel required for longitudinal reinforcement:   As per code IS456:2000; Therefore, = 1701mm 2 0.8% steel = 0.8*500*500/100 =2000mm 2 As per code IS456:2000, minimum reinforcement required for column design is 0.8% of concrete area. Hence, we should design the column for minimum reinforcement required.   As per code IS456:2000, minimum reinforcement required for column design is 0.8% of concrete area. Therefore, A s =2000mm 2 Use 16 mm steel bar as main reinforcement. Area of 16mm steel bar = 201 mm 2 . Therefore, No. of bars = 2000/201 = 9.9 Provide 10-16mm steel bar as longitudinal/main reinforcement steel .  

39. Calculation for tie reinforcement:   As per code IS456:2000; Diameter of tie bar ≥ diameter of bar used as main reinforcement/4 Therefore, diameter of tie bar ≥ 16/4 = 4mm   Therefore , use 8mm as tie reinforcement. Spacing for tie reinforcement:   As per code IS456:2000; Spacing: (1) Least of lateral dimension of the compression member = 500mm (2) 16*(smallest diameter of main the longitudinal reinforcement) = 16*(16) = 256mm (3) 300mm Whichever is the least has to be provided.   Hence, provide 8mm diameter of tie reinforcement @250mm c/c.   Column Reinforcement Detailing :   Figure 4.2: Column Reinforcement Detailing  

40. Summary for column 707   Size: 500 mm x 500 mm Clear cover: 40 mm Reinforcement: Provide 10 – 16 mm φ as longitudinal/main reinforcement. Provide 8 mm φ @ 250 mm c/c.
