11.2.4 Lateral Buckling

It has been stated earlier that the depth of a beam is very important in resisting a given bending moment and also to keep deflections small. However, if the depth is too great as compared to the width, the beam may buckle sideways due to the ‘column effect' (see Figure 11.7). The compressive forces in the upper fibres of a beam have the same effect as those in a column and the tendency to buckle increases as the beam becomes deeper and thinner (see Section 11.7.1 for details).
