Lateral buckling in beam is _________(a) does not occur in beam(b) one dimensional(c) two dimensional(d) three dimensionalI have been asked this question during an internship interview.Question is taken from Lateral Stability of Beams topic in division Design of Beams of Design of Steel Structures
Answer» The correct option is (d) three DIMENSIONAL For EXPLANATION I WOULD say: Lateral buckling in BEAM is three dimensional in nature. It involves coupled lateral deflection and twists that is when beam deflects laterally, the applied moment exerts a torque about the deflected longitudinal axis, which causes the beam to twist.
