Correct option is B
In steel structures, stiffeners are provided for specific purposes:
A. Bearing stiffener → To prevent local crushing of the web due to concentrated loading
Correct. Bearing stiffeners are provided under heavy concentrated loads or reactions to prevent web crippling.
B. Load carrying stiffener → To transmit tensile forces applied to a web through a flange Incorrect.
A load carrying stiffener is provided to transfer concentrated loads or reactions directly to the flanges, not to transmit tensile forces applied to a web through a flange. The definition given is misleading and not standard.
C. Diagonal stiffener → To provide local reinforcement to a web under shear and bearing
Correct. Diagonal stiffeners help resist high shear stresses and improve web stability.
D. Intermediate transverse web stiffener → To improve the buckling strength of a slender web due to shear
