1.	The requirement of effective bracing is(a) it should not have sufficient strength not to withstand forces transferred to it by beam(b) it should not have sufficient strength to withstand forces transferred to it by beam(c) it should have sufficient stiffness so that buckling of beam occurs in between braces(d) it should not have sufficient stiffness so that buckling of beam occurs in between bracesI have been asked this question at a job interview.Question is taken from Factors affecting Lateral Stability in section Design of Beams of Design of Steel Structures
Answer» Correct choice is (C) it should have SUFFICIENT stiffness so that buckling of beam OCCURS in between braces Easy explanation: The requirements of effective bracing are (i) it should have sufficient strength to WITHSTAND forces transferred to it by beam, (ii) it should have sufficient stiffness so that buckling of beam occurs in between braces.
