1.	Characteristic feature if lateral buckling is ___________(a) entire cross section do not rotate as rigid disc without any cross sectional distortion(b) entire cross section rotates as rigid disc without any cross sectional distortion(c) entire cross section rotates as rigid disc with cross sectional distortion(d) entire cross section do not rotate as rigid discThis question was posed to me in homework.Question is taken from Lateral Stability of Beams topic in portion Design of Beams of Design of Steel Structures
Answer» Right choice is (b) entire CROSS section ROTATES as rigid disc without any cross sectional distortion Explanation: The characteristic feature if LATERAL buckling is entire cross section rotates as rigid disc without any cross sectional distortion. This behaviour is similar to axially compresses long column which after initial shortening in axial direction, deflects LATERALLY when it buckles.
