Question

In shear design of an RC beam, other than the allowable shear strength of concrete (${\tau }_c$), there is also an additional check suggested in IS 456-2000 with respect to the maximum permissible shear stress (${\tau }_{cmax})$. The check for $\left({\tau }_{cmax}\right)$ is required to take care of

• A. additional shear resistance from reinforcing steel
• B. additional shear stress that comes from accidental loading
• C. possibility of failure of concrete by diagonal tension
• D. possibility of crushing of concrete by diagonal compression

Answer 1

The correct option is D possibility of crushing of concrete by diagonal compression

possibility of crushing of concrete by diagonal compression
