Maximum strai...

Question

Maximum strains in an extreme fibre in concrete and in the tension reinforcement (Fe-415 grade and $E_{s} = 200 k N / m m^{2}$ ) in a balanced section at limit state of flexure are respectively

Open in App

Solution

Maximum strain in extreme fibre of concrete = 0.0035

Maximum strain in tension reinforcement Fe 415 and $E_{s} = 200 k N / m m^{2}$

Maximum Strain
$= \frac{0.87 f_{y}}{E_{s}} + 0.002$

= 0.0038
