The maximum strain in the tension reinforcement in the section of flexural members shall not be less than

where $f_{y}$ is the characteristic strength of steel and $E_{s}$ is the modules of elasticity

- 1
  
  $\frac{f_{y}}{E_{s}} + 0.002$
- 2
  
  $\frac{f_{y}}{1.15} E_{s} + 0.002$
- 3
  
  $1.15 \frac{f_{y}}{E_{s}} + 0.002$
- 4
  
  none of these
