ABSTRACT
This chapter is concerned with intereaction buckling restraining actions, and presents approximate methods for predicting their effects. It also presents an extension of these methods to beams with overhanging segments. The chapter describes the method has been extended to allow the approximate analysis of the inelastic buckling of braced and continuous beams. The continuity between the adjacent segments of a continuous beam during buckling induces interactions between them. The chapter demonstrates that the conservative nature of the zero interaction method of approximation, the increased accuracy of the improved method. The internal restraints are associated with the antisymmetry about the brace point of the bending moment diagram, and with the jump in the bending moment caused by the concentrated moment. When the adjacent segments of braced beams are identical and have identical symmetrical bending moment diagrams, the segments buckle with zero interaction, and both segments act as if unrestrained.
