Question

The maximum strain in the tension reinforcement in the section at failure when designed for the limit state of collapse should be

• A. $>(\frac{f_y}{1.15E_s}+0.002)$
  
  where, $f_y=$ Characteristic strength of seel, and $E_s=$ Modulus of elasticity of steel
• B. $<(\frac{f_y}{1.15E_s}+0.002)$
  
  where, $f_y=$ Characteristic strength of seel, and $E_s=$ Modulus of elasticity of steel
• C. exactly equal to $(\frac{f_y}{1.15E_s}+0.002)$
  
  where, $f_y=$ Characteristic strength of seel, and $E_s=$ Modulus of elasticity of steel
• D. $<0.002$

Answer 1

The correct option is A $>(\frac{f_y}{1.15E_s}+0.002)$


where, $f_y=$ Characteristic strength of seel, and $E_s=$ Modulus of elasticity of steel
To ensure ductility the maximum strain in tension reinforcement in the section at failure shall not be less than $\frac{f_y}{1.15E_s}+0.002$
