A steel section is subjected to a combination of shear and bending actions. The applied shear force is \(V\) and the shear capacity of the section is \(V_s\). For such a section, high shear force, as per IS 800:2007, is defined as

1. V > 0.6V_s
2. V > 0.7V_s
3. V > 0.8V_s
4. V > 0.9V_s

Correct answer: V > 0.6V_s

Solution

As per IS 800:2007, a section is considered to be under high shear when the design shear force exceeds 0.6 times the shear capacity. This affects the design bending strength and interaction checks. Hence, the correct condition is \(V > 0.6V_s\).
