In a reinforced concrete section, the stress at extreme fibre on compr – InterviewSolution

1.	In a reinforced concrete section, the stress at extreme fibre on compression side is 6MPa. The depth of neutral axis is 60mm. The grade of concrete and steel are M20 and Fe415 respectively. Assuming linear elastic behaviour of concrete, the effective curvature of the section (in per mm) is____×10−64.4
Answer» In a reinforced concrete section, the stress at extreme fibre on compression side is $6 M P a$ . The depth of neutral axis is $60 m m$ . The grade of concrete and steel are $M 20$ and $F e 415$ respectively. Assuming linear elastic behaviour of concrete, the effective curvature of the section (in per mm) is____ $\times 10^{- 6}$ 4.4
