Q. For a given loading on a rectangular plain concrete beam with an overall depth of 500 mm, the compressive strain and tensile strain developed at the extreme fibers are of the same magnitude of 2.5×10-4. The curvature in the beam cross-section (in m-1, round off to 3 decimal places), is _
Solution:
Given,
ϵ=ϵt=ϵc=2.5×10−4
y = 250 mm = 0.25 m
As per flexure formula:
=0.001m−1
