The recent specification requires that lateral bracing must be provided to resist lateral forces and ensure stability of main girders. Based on the specification the unbraced length should not be geater than six meters and thirty times of the flange width for I section plate girders. Since no requirements related to lateral bracing are provided in the clause of composite girders, the requirements for plate girders have been applied correspondingly to composite girders. Lateral buckling modes of composite beams under negative bending differ from those of plate girders. The bucling modes of a composite beams may be assumed as the same modes of a inverted tee sections whose tip of the stem is hinged. The lateral buckling equation of an inverted tee section with a hinge is herein derived based on Vlasov's theory. Concludingly the minimum unbraced length of composite girders can be increased into about fifty times of the lower flanges from the buckling analysis. Requirements for the plastic design method ave also discussed in the present paper.
