An R.C. shert column, with 300 mm × 300 mm square cross section is made of M20 grade concrete and has 1 members, 20 mm diameter longitudinal bars of Fe 415 steel. It is under the action of a concrete axial compressive load. Ignoring the reduction int he area of concrete due to steel bars, the ultimate axial load carrying capacity of the column is
-
- 1659 kN
- 1548 kN
- 1198 kN
- 1069 kN
Correct Option: D
Pu = 0.4 fck Ac + 0.67 fy. ASC
= 0.4 × 20 × (300 × 300) + 0.67 × 415 × | ![]() | 4 × | ×202 | ![]() | 2 |
= 1069 kN
