1.	As per IS 800:2007, shear lag effects in flanges may be disregarded for internal elements if(a) bi ≤ L0 / 10(b) bi ≤ L0 / 20(c) bi > L0 / 10(d) bi = L0 / 20This question was addressed to me in an interview.Enquiry is from Design Strength of Laterally Supported Beams topic in section Design of Beams of Design of Steel Structures
Answer» Correct answer is (a) bi ≤ L0 / 10 For explanation: As per IS 800:2007, SHEAR lag effects in flanges may be DISREGARDED for internal elements if bi ≤ L0 / 10, where bi = width of internal element, L0 = LENGTH between points of zero moment in the span.
