A reinforced concrete column contains longitudinal steel equal to 1 per cent of net cross-sectional area of the column. Assume modular ration as 10. The loads carried (using the elastic theory) by the longitudinal steel and the net area of concrete, are Ps and Pc respectively. The ration Ps/ Pc expressed as per cent is
-
- 0.1
- 1
- 1.1
- 10
Correct Option: D
Strain in steel = strain in concrete.
⇒
Load on steel Ps = εs Es Ast
Load on concrete, Pc = εc Ec. Aco
| = 0.01 | Ac |
| = 10(m) | Ec |
| ∴ | = | = 0.1 | ||
| Pc | εc Ec. Aco |
