Home » Concrete Structures » Concrete structures miscellaneous » Question

Maximum strain in an extreme fibre in concrete and in the tension reinforcement (Fe-415 grade and E_s = 200 kN/mm²) in a balanced section at limit state of flexure are respectively

1. 0.0035 and 0.0038
2. 0.002 and 0.0018
3. 0.0035 and 0.0041
4. 0.002 and 0.0031

Correct Option: A

Max strain in steel

= 0.002 +	0.87 f_y
	E_s

= 0.002 +	0.87 × 415	= 0.0038
	200 × 10³

For concrete max strain = 0.0035
