In reinforced concrete beams why flexural failure is preferable to shear failure?
Answer:
I would think that neither type of failure is preferable. Why would you even want it to fail?
Flexural failure has warning signs, such as cracks in the concrete. Shear failure is sudden and violent with no warning signs.
thats right coz it happens suddenly and harder to repair
'Flexural failure' in reinforced concrete beams, in my opinion is much the preferred failure as against shear failure. Reason, the bending moment is much less drastic failure in a structure than the fractioning of the post or beam which results in a more drastic structural failure than a simple or compound flexing or flexural failure which in a sagging configuration is less apt to create a structural failure of dynamic or extensive failure:
